At the end of May, Bitcoin hit a new high this year after a sustained surge, which began to reverse on May 25th and 26th. It once fell by 900 US dollars, a drop of more than 30%.
I'm sorry, but how is a $900 drop more that 30% this year? If you were right, bitcoin's price must've been about $2.5k, right? Otherwise such a drop is at best a 15% one. As for the causes of bitcoin still not recovering, I think that is mainly due to the fact that in 2017 serious people really started to notice bitcoin and not always they had good intentions. Cryptocurrencies became a serious threat to contemporary economy and especially banking system. Various governments started making attempts to regulate cryptos and exchanges. Such things are still happening from time to time, causing the panic selling.
