because of this sudden increase of the bitcoin price it appears to be possible to reach $900 price value by the end of this year it is not impossible because lately it is just on the $800-$820 and now the price suddenly jumped to its current price and as we can see we are now in the $864 price which is closer enough to the first mentioned price . I hope that it will continue or eventually become slightly stable on $864+ price and will never be dumped .
This is not a sudden increase. The price has been up for a few weeks.
