Topic: Can someone explain this simple question to do with BTC Wallets. (Read 1438 times)

since at every transaction in the bitcoin charges you as a transaction fee for payment confirmation in block of bkockchain .
i will suggest you to use official wallet of bitcoin which is blockchain.info , i i hope you will find blockchaain a better wallet than other and second one i will syggest use blockchain.info android app instead of desktop site .

Hi welcome to the community well you done a great job you brought some bitcoin and thas a nice move you can start do tradi g where you gonna buy some alternative coins so that you can able to sell that when the coin pump nor rise the price it self you can use bitcoin wallet base on your country if you have one.

I don't think it matters what wallet you use as long as it is secure. If you move it to an online wallet, you may not want to keep it there long term for security but you may need to have it there for making purchases or transfers.

You can do a lot of things with your btc wallets. Just start where all newbies should start at bitcoin.org website.

It is always not recommended to keep your coins in the exchange wallet , as you dont got any control on that wallets, exchange wallet should be used only if you want to sell your bitcoins, and as soon as you have bought it you should transfer to your hardware wallet or desktop wallet which is totally safe and you are in control of it. Dont worry about a small fee for transferring the bitcoins as this small fee will save you from getting into any scam and loosing your purchased coins.

Cons are big, one is that u don't actually control your own coins. Localbitcoin will go down and you don't have access to your coins.
Get yourself a mobile application. Thats how u will always have your bitcoins with yourself and you will always need only to show ur client your phone to he be able scan QR code and pay you.

I could write all night long about pros and cons, but you should know by now through this many posts above, that its not good idea in general.

Actually, i didn't think about this right away, but a decent graphic card might be suitable for altcoin mining.
Personally, i don't have a lot of experience in this field, but maybe somebody else can point you in the right direction. Maybe you could rephrase your question and ask if your GPU is suitable for altcoin mining in the altcoin subforum, i'm pretty sure they'll be able to help you over there

Mine altcoin with your GPU => deposit on an exchange => trade for BTC => withdraw to your wallet

Ok, thanks for the advice. Saved me time doing research on getting into mining then. I did know about bitcoin awhile back and did abit of research but ended up not moving forward. Now it seems obviously not worth it.

Still looking for a way to make some btc on the side though, once im out of newbie status signature campaigns look good, gives me an excuse to be active on a forum again. When i was like 13-15 that is all i would do. I became a moderator on afew as well, good communities, wish i kept in contact with some of those people...

Thanks for all the advice guys! (I feel like locking and ending the thread, but whatever lol)

You certainly won't make $5-$10 USD/month, but the hardware damage will probably exceed $5/month when you try to mine.

https://en.bitcoin.it/wiki/Non-specialized_hardware_comparison doesn't list the GTX960. The GTX295 hashes at 117 Mh/s.
https://linustechtips.com/main/topic/268826-is-mining-with-the-gtx-970-at-650-mhs-worth-it/ tells tales of a hashrate of 650 Mh/s.

Let's plug these numbers into coinwarz: http://www.coinwarz.com/calculators/bitcoin-mining-calculator/?h=0.65&p=2600.00&pc=0.00&pf=1.00&d=220755908330.37200000&r=12.50000000&er=637.04740000&hc=0.00
1 dollarcent a month IF you run 24/7, at current difficulty, reward and price... Not counting the power cost, the hardware cost,...  I'm pretty sure this 1 cent is already rounded upwards.

In reality, you seem to want to mine on workdays during working hours, 20 days/month, 8 hours a day... So divide this 1 cent by 4,6 (the one cent a month is when you would mine nonstop using your GPU). You'll need to mine in a pool for several years in order to reach enough coins to cover the mining fee... I'm pretty sure you'll need to mine forever in order to reach the minimum payout.

BTW: mining using your CPU instead of your GPU is even a worse idear.

Sorry to sound so harsh, but it's the reality... Nowadays, mining without an ASIC is like flushing your cash down the toilet.

What if i don't pay for electricity? I have a GTX960 as well. How much roughly do you think it can make running 8 hours a day for a month?
I just want to see it work, it would be fun i think, i wouldn't be doing it for actual money, but if i can make $5-$10USD a month, might as well since the computer is idle at night time.

Not anymore. Mining with Bitcoin Core was just removed in 0.13.0 because CPU mining is absolutely pointless. It wastes energy and will destroy your CPU.

Don't do it. It's pointless, it won't help, and you will be mining at a loss. You will also end up shortening the life span of your computer.

Forgive my ignorance, but can you mine directly from Bitcoin Core then?
I know mining is solving the blockchain transaction puzzles.
But since you are storing all the transactions on your PC anyway, doesn't that mean you are storing all the blockchains as well?
I am interested in mining since my PC is already on 24/7, would be nice to see how much btc i can net over a month if any.

Using Bitcoin Core means that you have the complete database of all transactions ever created on your computer and yes by running the software you are helping the network. The more nodes there are the more secure the network is. And without enough nodes, it would take ages for transactions to complete. Web wallets are no different in that they need to be running Bitcoin Core as well on their servers.

Yes, the Bitcoin network is all peer-to-peer. It's true that when you run Bitcoin Core you help the network (your node should be configured properly, meaning opened port 8333 and online most/all the time).

It may be easiest to explain it with Bitcoin's history. You see, without people running full-nodes as is done with software like Bitcoin Core, there is no network! Bitcoin only exists because of the people that run it. In 2007 there was no Bitcoin. Satoshi Nakamoto, Bitcoin's creator, in Jan 2009 launched Bitcoin by running an early version of what is now Bitcoin Core. It was only him on the network, so there was really no network. Satoshi had announced his project and soon a few others installed his software and connected to his node. This formed the network which has grown to be what it is today, which has thousands of nodes.

Bitcoin is based on nodes which produce blocks and transactions and relay this information to each other. When you run Bitcoin Core, you are one of these nodes. One key difference is that you no longer create blocks, you only relay them. Nodes which create blocks are called mining nodes, and this has largely become specialized. Together "miners" and others who run non-mining "full-nodes" form the entire network. When you use an online wallet like LocalBitcoins.com or Blockchain.info, they are running a Bitcoin Core node, and they pass along your transactions.

If you use online wallet, somebody else can have access to the keys to your money.

If you use a wallet on your computer, you are in charge (and anything bad happens it's only because of you).
This means you have to make backup of your wallet, you have to protect your system for trojans and keyloggers...
The history has shown that businesses that keep people's Bitcoin are not as safe as we'd like and some get hacked (or just ran with the money) now and then. They are big attraction too because of the amounts of money there.
So for most people - especially if you know more than average about the computers - the wallet on computer is the best way.

I advise you use a light wallet. You have most functionality you need and you don't have to download the blockchain. I use Electrum.
And yes, the transactions cost money. The fee is a couple of cents, not something scary. Most wallets can set the correct amount for that.

Thanks for the advice on Bitcoin Core and Localbitcoin. Yea Localbitcoin is great for buying bitcoin with money. After i start figuring out what to invest / work for BTC i probably will move away from there but for now it suits it purpose of allowing me to buy BTC for money then sending that BTC to various people for services / goods. If i need to receive small amounts of BTC i don't see any harm in using that as well since that will be my main source at the moment.

I understand it, but am still puzzled when you talk about Bitcoin Network, there is no centralised hub where this information is held, much like P2P networks, im guessing that people using Bitcoin Core somehow help the network of bitcoin users? Or any of the web-based wallets would somehow be aiding in the running of the 'network'?

Using Bitcoin Core is great as it's the "real" way to use Bitcoin (I mean you're actually participating as part of the network, which has different meaning than just using a web or even lightweight wallet). People don't really suggest newbies use Bitcoin Core because it can be more challenging to get up and running (including long sync time) than a web wallet where you just point and click, which might turn people off.

LocalBitcoins.com is great. It's possible to use LBC as a wallet, but that's not really what they are designed to be.  Instead you should think in terms of your own preferred coin storage and spending model. This will depend on how much you plan on storing and keeping secure as well as how often you'll make transactions. If you're planning on storing large amounts you really shouldn't use any online service because they can all be hacked and/or have legal issues or just be incompetent. An exception is a company like Coinbase. They are subject to the same pitfalls, but they are large, VC funded, and insured. They are more like a real bank. It's fine to use online wallets for smaller, quick spending amounts. I'd just spread balances around a bit.  Check this advice I gave for more info on securing coins.

Last, for your question about updating balances of backup copies... This is one of the coolest things about Bitcoin. You don't actually store coins on a computer drive (or piece of paper etc). What you are storing is a secret account number called a private key. The Bitcoin network keeps track of how many coins belong to each private key (it's actually more complicated, but this is a way to think of it). Whenever you use any copy of that key to send coins on the network it applies to all copies. There is also a "public key" associated with your private key (which is basically the wallet address you give out to receive coins) and it's tied the same way.  This means you could, for example, generate a safe Bitcoin wallet address (which consists of public/private key pair) and print that out on a piece of paper which you store in a safe. You could then send unlimited amounts to that address, anytime, and it would remain updated and secure without ever opening the safe!! This is called putting a "paper wallet" in "cold storage".

Still running on 0.12 here ... I honestly didn't know 0.13 is deterministic.

@OP: if 0.13 is deterministic, one of the two main reasons i gave is now void. core is still a lot bigger and it still takes a lot longer to synchronise compared to electrum/multibit HD, but it's up to you wether or not you chose this one

Several being less than 10 Gb. It is a significant reduction from the 80+ Gb that is normally required. The sync time depends upon your network connection and computer. For example, my computer with 4 cores and 8 Gb of ram can sync the entire blockchain in less than one day.

Not anymore. As of Bitcoin Core 0.13.0, a BIP32 HD wallet is used, so you only need to backup once. If you set a password or change on though you will need to backup again.

Well... Bitcoin core is great... The downside is that you'll have to synchronise your wallet... Basically download and verify all the transactions in all the blocks.
There are options to prune the blocks, in order to keep the used diskspace lower, but you'll still need several gigabytes of storage and several days to sync (if i remember correctly).

Also, bitcoin core generates random private keys, so you'll need to re-backup your wallet.dat very often, since new private keys will be added.

A HD wallet (electrum, multibit HD) uses a seed to generate private keys. If you saved the seed, the wallet can re-create all private keys from this seed, so can worry less about backing up.
A HD wallet also only stores the block headers, so it syncs really fast and it's really small (a couple of minutes + a couple of megabytes).

I personally like electrum the best because it gives you more controll over your coins. It lets you pick inputs, re-broadcast, export/import private keys while multibit HD hides a lot of these, more complex, features.
