Alright, thanks for explanation, so how do I download all blockchain? I downloaded bitcoin core -qt and where do I get all the blockchain so my balance would be up to date as It shows 0 btc now.
The complete blockchain will be only available via bitcoin core (at least I dont know any other way), because it changes roughly every 10 minutes (when a new block is found). The bootstrap.dat allows you to get plenty of the old blocks. Same with the .rar files I linked you. After you got them you start the client and it will be only a few days behind, which will be downloaded in a few minutes/hours depending on your network connection.
I have a wallet at blockchain.info and I would like to transfer It to bitcoin core qt so my funds would apear on my bitcoin core qt, how do I do that?
