One good tip would be to keep a back-up of your wallet so you don't lose your coins, and make sure it's actually a legit wallet not a trojan wallet that will just steal your coins.
Wow. its so hard when you`re new in a branch.What you mean with a backup of my wallet? ...and how do i know its a legit wallet and not a trojan wallet?
And btw i started to synchronize my wally like 10 hours ago. and it almost stoped at 89%..its very slow. so basically i dont even have a wallet yet.Basically with 3 good computers i can get like 1 bitcoin wich is about 7$ a day at the moment...doesnt sound much profitable.
. Dont know how expensive is electricity there...but here in my country i dont think is that expensive .
DannyHamilton Buying bitcoins wouldnt bring me any profits i think.i mean..its just a currency exchange. but offcourse since i give cash money in exchange of bitcoins i can get some small profits. it seems i`ll have to read more to be safe in this `game`. trojan wallets...wallet backup...new terms for me:).
Bitcoin is a currency. To get bitcoin you do the same things you would do in any other currency:
- You can sell stuff you own and accept payment in bitcoin.
- You can provide a service that someone else wants and accept payment in bitcoin
- You can exchange your local currency for bitcoin using a bitcoin currency exchange
- You can beg for bitcoin and hope that some kind soul will donate to you.
Like with any other currency, to bring a profit you need to make sure that your costs associated with your activity are less than the revenue you get from the activity.
In addition you can mine for bitcoin if you have a really good graphics card (or FPGA) and access to really cheap electricity.
Synchronization in the reference client (Bitcoin-Qt) takes a very long time the first time you do it. The reference client (Bitcoin-Qt) is a "full node" and as such it downloads/synchronizes the entire blockchain containing every bitcoin transaction that has ever occurred since bitcoin began a bit more than four years ago and validates that every one of those transactions is legitimate. You may also want to look into one of the "lightweight" wallets such as Electrum, or Multibit, or you might want to consider a web hosted wallet such as blockchain.info/wallet.
To spend bitcoin requires private keys for a cryptographic signature on the transaction. Most of the wallets take care of maintaining your private keys for you, so you generally don't see them or know what they are. However, if your hard-drive crashes, or you somehow loose access to the file that stores those private keys, you can never again spend any of the bitcoins that were in that wallet. This is why people recommend backups. A backup would store a duplicate copy of the private keys in a safe location. In the case of the Bitcoin-Qt wallet the file that needs to be backed up is called "wallet.dat".
To know that the wallet you are using is a legit wallet you have a few options.
You could download the source code, read through it all and make sure that it is programmed exactly the way it is supposed to be. Then you can compile that source code yourself using a compiler that you trust.
Many people have already done this. If you trust that the community would alert you if there was something malicious in the program, then you can download the already compiled program from a trusted source such as bitcoin.org (or wherever the community states that client you choose to use is hosted).
With 3 good graphics cards you might be able to get 1 BTC every 3.5 days (not 1 BTC every day). It doesn't matter much how good the computer is, it matters a lot how good the GPU is, and no, mining isn't very profitable unless it is done in a large way with cheap electricity.
