ethereum this now good time to buy
after release good news information about second hard fork
and after dump this now trend can up, maybe price can up t 0.025 - 0.03 every one etherum

to me it is not good time to buy Ethereum, as people are not going to invest their bitcoin as the price of bitcoin is expecting to increase too high therefore you should wait for some time.

There will be another hard fork, the price might even drop further.

During the last couple of weeks, the Ethereum network has been the target of a sustained attack. The attacker(s) have been very crafty in locating vulnerabilities in the client implementations as well as the protocol specification.

While the recent patches have led to an overall increased resiliency in the client implementations, the attacks have also demonstrated that a lower-level change to the EVM pricing model is needed.

For many users, the most visible consequence is probably that they are having difficulties getting transactions included in blocks, and full nodes are facing memory limitations in managing the bloated state.

This is our strategy to address these issues:

As a temporary measure to minimize the effects of the most recent attack, we recommend all miners to lower the gaslimit to 500K gas.
A hard-fork based on EIP 150 version 1c will be put into effect at block 2457000 [see below]. This will reprice certain operations to correspond better to the underlying computational complexity.
A second hard-fork will follow shortly after, aimed at reverting the current “state-bloat” introduced by the attacks. This second fork will serve to remove accounts which are empty; lacking code, balance, storage and nonce == 0.
We have implemented the changes required in the clients and are currently extending and adding tests in an effort to prevent the introduction of consensus-breaking vulnerabilities.

And as a reminder, the Ethereum Bug Bounty is open and includes the new hardfork-implementations.

EDIT: Fork block has been moved to 2463000 in order to accommodate even more testing.

Not sure about that. The Ethereum price has not dropped much. So we may wait a bit longer to buy.

This is the best time to  buy ETH hence it drop its price which is  really an  opportunity for us  to buy even more because  it would surely  rise up on  upcoming months i guess and we could able to secure profits but still just invest on money that you could  able to  lose anyway because we dont know when price would  rise up.

Would wait a little but longer if you already have them and maybe buy more right now because the fact is that it lowered and it can maybe be very profitable if you now invest in it.
It wil go up for sure, I have no doubts about this to be honest.

The Ethereum price has dropped against the bitcoin in the last few weeks. That is a good time to buy.

Well I think you can so both things right now its not that it has a bad time right now but I think that I prefer buying right now indeed above it but of course its also depending on what you are doing with it and how long you want to hold it.

I think its time to buy the the Ethererum it has a great future and will rise more so I think it would be stupid to not buy it.
You can better sell it later when the price is higher right, you just need some patient.

The Ethereum is under constant development. So the price could rise in the long term. But for the short term, the price is volatile.

You might not have noticed, but ethereum is under attack.

What began over two weeks ago with spam attacks that led to large-scale ethereum node outages has escalated into a battle that has pitted the platform's developers against unknown antagonists. This might sound like an exciting Hollywood movie, but it's mostly been carried out on message boards and with code.

Shots were first fired at ethereum's big developer conference, Devcon2, with a mysterious message written in German and delivered via transaction method payload. The message said "Go home", but to those who have been following the network's contentious changes this summer, the full meaning was clear.

Since then, block creation and transactions have continued to be impacted, with nodes syncing up to the network more slowly. But while various fixes have since been implemented, the attacker continues to find vulnerabilities to exploit and, in turn, create new ways to launch denial-of-service (DoS) attacks.

The result: the network is being flooded with transaction spam.

Blockstack co-founder Muneeb Ali called it a "cat-and-mouse game" that could potentially continue to slow down transactions on the network, the second most popular by market cap.

Most of the attacks have thus far affected nodes running the Go-version ethereum client (Geth), the most popular implementation of ethereum, though Parity, an alternative client released at the conference, has been impacted in some instances.

The latest release, called "Dear Diary", aims to stop the "root cause" of many of the attacks with a technique called "journalling."

Anatomy of an attack

One problem that has emerged for client developers is that those behind the attack are constantly switching their tactics.

The attacker or attackers are deploying smart contracts to the ethereum blockchain, and then committing transactions that impact how clients handle data, slowing them down to the point that blocks and transactions become delayed.

(For a peek into what's going on, see the barrage of small transactions sent by the attacker to overwhelm the network).

The first line of attack targeted an out-of-memory bug, which the Geth team moved to fix in a subsequent software update.

"In ethereum one of the challenges is that we have this huge database that grows much faster for example than bitcoin," said ethereum developer Péter Szilágyi, who works on Geth, adding that the attackers have taken advantage of this issue.

"We never thought about this attack vector," he added.

The focus on Geth has prompted some users to spin up nodes using Parity. In the wake of the first attacks, most miners made the switch.

However, Geth is still by far the most popular client, numbering nearly 7,000 nodes compared to Parity’s 900, although the numbers are constantly fluctuating.

Meanwhile, Ethereum Foundation IT consultant Hudson Jameson chose to emphasize that the Geth team has been able to fix every issue that's been thrown at it so far. This argument was also stressed by ethereum miner Jonathan Toomim, who called the fixes, deployed within days, "impressive".

"The network will go on, and these nuisance attacks will stop eventually," he reasoned.

Yet for how long remains unclear. Each time Geth or Parity releases an update, the attacker finds a new vulnerability.

Those behind the attacks don't seem to mind the cost of doing so, having spent thousands of dollars worth of ether – the cryptocurrency of the ethereum network – to fuel the attacks.

"To date, the attacker has spent over $3,000 worth of ether, solely in gas-costs," Jameson estimated.

Impact on users

Many argue that the attacks are an inevitable result of the way ethereum is designed, and that it has a  "large attack surface."

More on-platform capabilities means that there are more opportunities for trouble, at least compared to other blockchain networks, which are less ambitious..

"The larger problem is that the way ethereum is designed. There’s too much exposure so the attacker can trigger certain things or send certain types of transactions," Ali said. "Think of it this way: ethereum allows people too much freedom over what they can do to someone else’s computer."

Even if Geth nodes are no longer crashing completely, however, it has resulted in an overall slower network, making ethereum less available to anyone who want to spin up a smart contract or send a transaction.

Since the attacks, some users have reported having problems accessing their funds with Mist, the popular ethereum wallet.

One user even observed when switching pools that mining profitability has decreased for smaller pools, which is potentially a concern for an ecosystem that doesn't want bigger miners to have more control.

The network is also more vulnerable overall if all of its nodes are not functioning properly.

"Causing large portions of the nodes or miners to drop off the network, or fall behind, is naturally rather severe, since such attacks can be a prequel to a double spending-attack," Jameson said.

However, some users seem unfazed, with many developers continuing to work on other projects. Two ethereum projects, FirstBlood and SingularDTV, held crowdsales to raise project funds amid the attack.

Finding a fix

As far as reducing the impact, developers have come up with ideas for how to fix the problem with medium- to long-term changes, in what Jameson calls an "ecosystem-wide effort."

"One of the solutions is to make it more expensive to perform these kinds of attacks," Szilágyi said.

He explained that raising the prices for certain ethereum commands might mean protocol-level changes to Metropolis, ethereum's next big software release that is intended to be more developer-friendly.

Jameson also mentioned rebooting the bounty program, through which developers can earn bitcoin for detecting and reporting bugs. "That way people can submit their flaws legitimately instead of attacking the network," he said.

However, his hope is that the detection of these bugs will make ethereum stronger in the end.

"In the long-term, these attacks increase the resiliency of the Ethereum network," Jameson added said, arguing that the diversity of clients handicaps an attack from impacting all nodes.

Role of the foundation

Others seem to think that it's unclear how quickly that ethereum will recover.

"The Ethereum Foundation is trying to downplay them and spin the situation in a good way, saying that attacks will help to harden the network," ethereum classic lead developer, Arvicco, argued.

While the comments are not surprising given that he leads an alternative project, they point to the overall sentiment of those who have been critical of the organization that funds protocol development and its handling of the situation.

Others remain uncertain what to take away just yet.

Ali said he thinks ethereum team has done a good job thus far in addressing the vulnerabilities.

Still, he suggested there might be no end in sight should ideological motivations to disrupt the network continue unabridged, but that this ultimately might be the best outcome.

I hold some ETH at the moment and honestly I don't know what to do with them.
Selling at this price doesn't make much sense, nor does buying at this price makes sense, since it's actually quite high.

Luckily I don't have a lot.

I think time to sell if the price didn't go up significantly during Devcon I don't think there is any fundamentals to drive the price up for now.

You are right about that but I think that selling them right now is not an option you can better hold and buy more and wait on a better price.
Its gonna rise to a higher amount without any doubts.

In the short term, the price of the Etheruem might rise in terms of US dollar, but it might drop in terms of bitcoin.

The current price of 0.021 is certainly higher than the 0.015 you mentioned. But it might not be a bubble.

You can right now buying but I think it will go down more so we most likely better wait on a better price honestly.
Lets see what is gonna happen with it, just be patient.

i am not buying it at the moment because it is always risky to buy when the price of ethereum is in a bubble.

instead i will wait for a big or even slow price drop to at least 0.015-0.017 then buy it back.

It ain't, because it has now started dropping after the hack that took place in it...
I think being too speculative would be silly here as the price is just holding because big whales have their investments that they currently don't want to ruin such an opportunity that has created a lot of mess these days, but be sure that you will see it ending in the dust very soon...

There are still active development of the Etheruem.

Can This 22-year-old Coder Out-Bitcoin Bitcoin?

Vitalik Buterin, creator of the fast-growing new cryptocurrency network Ethereum, wants to use his technology to disrupt, well, everything.

The chaos started in the morning hours of Friday, June 17. At 8:15 a.m. Berlin time, Griff Green, a community organizer for Slock.it, a German tech firm, blared an alarm: “EMERGENCY ALERT!” he wrote in a public chat channel.

“PLEASE DM A SLOCK.IT MEMBER ASAP!!!” he continued, addressing stakeholders in a blockbuster venture codeveloped by the company, the DAO (pronounced like the Chinese philosophical tenet), which had been hailed as the most successful crowdfunded project of all time. Three people replied immediately: “Uh oh.” “What is going on?” “Oh shit.”

Green waited another half-hour before adding, “We aren’t sure what is happening but the DAO is in an emergency situation.”

The letters in DAO stood for decentralized autonomous organization, and the idea was that the startup would be a new type of corporation—built on the technology that powers cryptocurrencies, such as Bitcoin—with algorithms executing the strategy instead of human managers. Specifically, its coders intended the DAO to function like a venture capital firm—a kind of Kickstarter-like Kleiner Perkins.

A month earlier thousands of investors had plowed some $160 million into the experimental company. Their contributions were made in Ether, a year-old digital currency (and rival to Bitcoin) that they had exchanged for virtual tokens. The DAO’s creators had designed the software to execute the will of its token holders, based on a tally of their collectively computed votes.

The investors had been assured the money was safe when they deposited it in the DAO. The network powering it was “more secure than every bank put together,” Stephan Tual, one of the DAO’s originators as well as a cofounder and the chief operating officer of Slock.it, had boasted during the project’s funding campaign.

But now a hacker had broken in and was in the process of pilfering their funds. Green recommended that constituents spam the network—clogging its pipes—to slow down the thief. “Yeah sorry guys. this is not a drill,” Green added lamely.

n the chatroom, emotions ran high. “Are we fckd?” one person asked. “Man what a epic failure,” ranted another. “I’m in the bathtub, about to throw a toaster in!” said a third. Another person summarized: “:fire: :fire: :fire: :fire: NOBODY PANIC :fire: :fire: :fire: :fire:” Many drew comparisons to Mt. Gox, a Japanese virtual-currency exchange—once the largest of its kind—that had collapsed in a catastrophic $460 million hack two years prior. Were they now watching the DAO implode too?

By the time Slock.it had regained control the next day, the hacker (or hackers) had stolen more than $50 million—nearly a third of the DAO’s funds. As people scrambled to make sense of the calamity, one name rang out in the forum. “Where is Vitalik?” asked one. “Wake up vitalik,” pleaded another. “Vitalik, our alien overlord, please save us.”

“Calm down,” came a reply. “Vitalik is working on it.”

A month after the hack—and mere days after presiding over a controversial vote to initiate a “hard fork” process that would recover the DAO’s stolen funds and make whole its backers—Vitalik Buterin is listening impassively to a guy wearing a beanie cap shaped like a Pokémon dragon. “This is a really tricky game,” says the man in the hat, an assistant professor of computer engineering, as he excitedly begins to lay out a complicated logic puzzle. But before he can get too far, Buterin quietly interrupts with a clever solution. “Oh,” says the Pokémon prof, crestfallen. “That’s actually pretty cool.”

Buterin (No. 31 on 2016 40 Under 40 list), a 22-year-old coder, is visiting the Cornell University campus for a boot camp organized by IC3, or the Initiative for Cryptocurrencies & Contracts, an academic consortium that researches peer-to-peer payment systems. Roughly two-dozen programmers are gathered around a long conference table inside Gates Hall (as in Bill and Melinda), the brand-new, steel-plated home to Cornell’s computing and information science departments. The air is thick with talk of “stochastic dominance,” “Merkle trees,” and “zk-SNARKs.”

Although he’s among the youngest in the room, Buterin is indisputably the star of the group. He is, after all, the wunderkind creator of Ethereum, the network on which Ether runs. And Ether is now the biggest rival to Bitcoin, the $10 billion cryptocurrency that mysteriously burst onto the scene less than a decade ago.

The Ethereum price is around $12 now. So it is still rising from a few weeks ago. It is just consolidating now.
