This are pre launch tokens only, how do it work on launch? How can i change pre launch tokens to real QTUM?
thanks a lot

Qtum will be the first POS smart contact platform.
one Qtum will worth 50$ in one year.
great news! I'm in! good luck all people, who joined this campaigns. one Qtum will worth 50$ in one year.

When will the token go to the exchange?

So... I was spammed...
When will PoW arrive?

Daily Test Network Update #3:
Leading up to our June 28th Test Network release, we will be providing daily updates that explain the work that goes on behind the scenes. Yesterday we went over the 5 more points, and today we focus a lot on the Proof-of-Stake portion of the Test Network.
11, Change all output strings Bitcoin -> Qtum, BTC -> QTUM
Replace all instances of bitcoin and BTC with qtum and QTUM (Just the output strings, not the actual class/variable names and not the code comments)
12, Increase Script limits to suitable values
There are a number of limits in vanilla Bitcoin that restrict our usage of smart contracts. These limits should be relaxed:
maximum data push size: 1Mb
maximum stack size: 1Mb
Test for other limits that we run into with large scripts caused by contracts.
13, Consensus/Chain parameters for PoS
Consensus/chain parameters for PoS
The consensus provide parameters that will affect the creation of new blocks in the network.
The PoS limit need to be added in order to determine the initial difficulty for PoS.
The halving interval is 4 years (target) and there will be 7 halving intervals.
Block target is set to 128 seconds.
4 tokens per Block (Approximately 1% inflation per year for 4 years)
2 tokens (Slightly more than .5% inflation per year for 4 years based on 100 million original tokens .5% of 104~ million after 4 years)
1 token
.5 tokens
.25 tokens
.125 tokens
.0625 tokens
The last PoW block need to be defined and set to 5000 for the main net. The reward for PoW block is 20000 coins, the reward for PoS block is 4 coins. The Proof-of-Work blocks will be mined by the Qtum development team.
14 , Update of block/block-header parameters for PoS
The general rule for the header is to keep it as small as possible.
Four parameters are needed for PoS in order to work:
1) Block signature, that is the signature of the whole block, signed by the block creator
2) Block type (Proof Of Work or Proof Of Stake)
3) Previous stake location, need in order to confirm the block validity, mandatory for PoS
4) Staking time, the time when the staking transaction was created, mandatory for PoS
Block signature must be a parameter. The parameter need to be in the header due to the segregated witness which split the block delivery into header and transactions that can be required from any user.
The other parameters can be extracted from the PoS transaction. Whether or not to include those 3 parameters in the header too can be discussed. The block header is downloaded before the whole block, not including those parameters in the header will prevent doing PoS checks to the header before downloading the whole block. Blackcoin download the whole block before the checks and put those parameters into the Block.
15 ,Proof of Work/Stake Kernel Update
The source code for PoW and PoS kernel is kept into the files:
pos.h
pos.cpp
pow.h
pow.cpp
The location of the files is according to master-pos, in Blackcoin the location is kernel.h and kernel.cpp.
We need to decide if we will keep it or use different structure for organization of the code for PoW and PoS kernel.
The version of the stake modifier that will be used is the second version.
Block difficulty, masks, modifiers, time-stamps are all used here, so this is important parts for PoS.
Please see the Roadmap below for more information:
Please remember that we have an event in Shanghai on the 28th so please RSVP if you plan on attending:
Qtum will also be sponsoring a Hackathon in Russia, with 8500 QTUM tokens. For more information, please see:
Qtum is hiring! If you have experience in Blockchain technology, and can handle working in a changing industry, get in touch with us.
thanks for the updates!

I understand you want to get the news out about Qtum,but why spam inboxes? Very annoying to receive random messages about receiving a PM from a project which I had and still do not have any interest in. Just like back in the day when Ethereum shills spammed the inboxes of reddit users telling them to buy up ETH.
I also received a message, and shit Im not f**king interested in this bullsh*t coin!!! 
Maybe they are just annoying people who are not advocates of their project. But to be honest, I still believe some accusations of Gleb towards this one. My impression is that, the Qtum team were just pressured to come up with solid outcome because they are trying to prove that all the allegations are not true. With such progress, that's a positive development for all the investors.
Yes, not all of my accusations hold water, but the ones that do should be concerning. I like the part where fairly new Chinese exchanges whose principals are directly associated with Team Qtum are the only exchanges currently trading the Qtum token, and even have the pre-launch token represented on coinmarketcap.com. How the fuck did they pull that ruse outta their yellow asses?
My other favorite concern is when it was disclosed that Patrick Dai was Steven Dai, but all of Team Qtum stuck it up our asses, adamantly proclaiming that such was a lie, then Patrick came forward and stated that it was in fact true, further expressing that EVERYBODY in his camp, including angel investors, were well aware of such, and further proclaiming that it's common practice for not only a Chinese person to maintain an English name, but change it to another English name when the wind blows.
But none of the above matters because Qtum in a non-profit entity and IS NOT an investment vehicle as they've stated myriad times, hence being chartered in Singapore where Qtum is forbidden to garner more than 5M SGD (less than U$5M) in its coffer during the lifetime as a Singaporean non-profit.
oh stupid gleb come back now.
if 99% people think one thing is right, then it's wrong.
i am glad you are always like that 99% people.
haha

Is the crowdsale still on?
The Crowdsale ended on March 21st, but the test network will be released on June 28th, allowing you to acquire test tokens and check out the system. The main network launches in September, which is when participants can withdraw their coins from the exchanges.
June 24, 2017, 08:29:52 AM
The last time we did an event in Shanghai it was streamed, but we used a Chinese service. We can try to upload it for others to see if streaming isn't possible for Western audiences.
Hopefully all goes well with the event. I hope to view it (hopefully subtitled in english). Let's just say I have a lot of hope. June 24, 2017, 01:32:57 AM

friend, I don't think that you but in general
in the west realize how BIG Qtum is in China.
Over $60million 24hr volume and it's not released yet!
Look the troll that into you if don't understand this

they dont care about it Gleb as long as their profiting by being an early investor, but I will say pity to those who will soon fall to trap and will buy the crap for them to exit. 
Qtum has the second most volume on Chinese exchanges after BTC, more than even ethereum and it's not even on a testnet release yet. It's a pity there was so much fud posted here, all it served to do was to prevent most Westerners from getting a piece of the pie.There are a lot of technical improvements on Ethereum that Qtum is doing and the team working on the code is top notch.
Anyways, I love the ridiculous conspiracy theories about how the exchanges are being rigged by the Qtum team. What is the conspiracy, that they're spending $40 million a day in BTC generating volume at 35x the ICO price? How nice of them to pay 35x what people paid in the ICO then.
The reality is that the scam criers are too shortsighted and too lazy to learn Chinese to actually see all the work they've done with the Chinese community to get Qtum ahead of other cryptos. So just keep sitting there posting gibberish. I like how at first it's basically libelous posts about the creator being a thief (if you really have evidence of them stealing millions why not call the police?! I'm sure interpol would be interested in an international theft of millions), but since that didn't pan out now every exchange that has literally tens of millions in volume per day must be part of some bizarre conspiracy to pay people dozens of times what they spent in the ICO. Is that the story you tell yourself to feel better about completely missing out on what will be THE top crypto in China?!
We stay on qtum project that will a big revolution.
