You can see indeed that the value of Bitcoin is going to be higher and that many people are now waiting for the right moment to sell it so that is really nice.
But you dont even know what will happen in the future and that is the problem of Bitcoin but that is just only risky also.
The issue with the bitcoin is that you never know where it is heading. If its going in an upward direction, it does not means that it will keep on rising or if it is going in downward direction, then also it does not mean it will countiune in that direction. You cannot predit the price of this coin. One day it can be as high as 750$ and the other day it can fall to as low as 500$. This unpredcitable nature of bitcoins makes it very difficult to guess what wil be the furture price of this coin.
