$25,000 USD is 303% increase of Bitcoins current price of $6,200 USD. Last years bull run from $3,500 USD to $19,200 USD is 400% increase. So if what happened last year will happen also today with no other problem like another hacking incident of a major exchange site or maybe fake news, $25,000 USD is possible by end of this year.
I also has the same expectation from bitcoin price that it will reach to 25000$ very soon even before ending 2018. In fact it was even expected in in very beginning of 2018 that bitcoin price will very soon reach to 25000$ but unfortunately it could not happen, but this time I am too much confident that bitcoin price will easily reach to 25000$.
