End of 2017? I didn't expect that the price will be fast on $19,000 and I'm thinking that this year bitcoin will end at $25,000. Many will say that it's not possible but why not give it a try, it's just a speculation and there's nothing wrong for speculating this amount. Since everyone's speculation before which is just an impossible one starting to be in reality.  It will be a good one if bitcoin hit $30,000 at the end of this year.
