I'm actually not surprised by $1000 drop, but was quite worried when it came all the way from $20,000 to almost $6,000 which I think was the biggest drop in last 3 years. I think it made many new comers, especially those who entered crypto at the backend of last year scared, so they simply keep away from bitcoin (and cryptos) for the moment, and whose with experience probably either exited or simply holding for the moment, so there is no much actions.

So, I guess the next catalyst would be Consensus 2018 conference in mid May. It usually attracts more than 30 ~40,000 people, so it will probably push big investors to join the cryptos after seeing wonderful developments during the past year.

Talks on regulations have also kept many people away from cryptos, but that's actually a good thing for the development of cryptos. So, I hope after everything is clear, we may again see huge gains starting from this April, but like always happen, will see price fluctuations.
