Yes bitcoin had affected many lives either positively or negatively. I had encountered many live examples. One of my friend is doing bitcoin trading to manage his family means he earns b about $400 monthly. And I had another friend who always suffers losses and he is frustrated with his life because after getting such losses one can't keep calm you know. So bitcoin have both good and bad. It depends what your luck choose.

I don't calculate on daily basis but my target is to earn 1 btc per month and I am successfully earning that amount from altcoin trading and signature campaign is a bonus for me.
