last week only $3400, now it's $4400
even I don't buy cheaper coins at the end of july, but I am still win.

Yes agree 1000$ profite for only one week is great profit for traders just now. I don't know if bitcoin price next week will up +1000$ but everything in this world is possible. So I will keep buying small amounts of BTC because I think next few month Btc price will be more than just now
