On July 2017, price of bitcoin was around $3000, in December 2017, Bitcoin got the new ATH of $20000, therefore, I think it's possible to reach $30k by the end of this year.
Don't want to sound negative but we kept saying this line since 2018 when BTC reached ATH then value goes down after couple of months.
The value of BTC at the moment isn't bad and yes, let's hope that it'll reach its ATH again this year or so as long as the crypto market is doing good.
