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
Bitcoin price is heading up so fast and I agreee that 5000$ isn't far away. But this trend could also slow down so there is possibility that price remains at 4000$ for a while. Anyway, I think that bitcoin is the most profitable investment at the moment, not just for traders, and everyone who can should put the money in. Let's hold our finger crossed that the price keeps rising.
