Hello all. Can anyone tell me how to track bitcoins. I know, using blockchain, but it any advanced way? I got only to blockchain Tree Chart and I have to click on every transaction to show other ones... but is there any way that I will check one BTC transaction and "search" if did bitcoins from there end on one exact another address?
I don't know of any explorers that can do it. Blockchain.info's transaction tree view is probably the best there is.
I mean is there any way to find out connection between two BTC addresses?
Yes: by transaction. But again, there's no known explorer that can make it easier.
And different question: If I know 2 BTC addresses, is it possible to find out if they are from same person (or wallet)?
No unless:
1. There's a transaction linking them (that you know of).
2. You have their wallet or master public key.
