I thought for a moment bitcoin is a key objective in seeking extra money from the internet. because I see for myself what was done by my friend from the trade bitcoin. he has managed to buy what he wants from bitcoin trading results. indeed if we want to try and keep learning to trade bitcoin, then the result will be very profitable.
This is interesting for I only hear about how people lose with trading. Can you tell is he trading altcoins or he is profiting from The Bitcoin fluctuations?
To the OP's question, yes Bitcoin is a serious thing to me. In fact more than a half of my hopes to become rich are connected to Bitcoin.
