Is bitcoin going to achieve 4000$ in the near future ?
Very possible, especially with how high bitcoin is right now and how much it has grown the couple of days. Just 12 hours ago Bitcoin was still at 3,450 and now it is at 3,664. Prices have risen so much the couple of days and they may continue to keep rising.
The problem is, everyone is anticipating for a drop in price for bitcoin, since I don't think that Bitcoin will continually be such a high price and of course it must fall soon, just how much will it fall.
