Is cryptocurrency done for?

As all of you may know Crypto currency took an unexpected turn, with bitcoin losing roughly fifty percent of its value from all time high 20k last month. Surprisingly I'm still looking at this as a bull. My question to you fellow steemions. Is it time to pull out or buy all the coins you can while they are cheap?

Would love your honest opinions with credible feedback sources if available.

I know a lot of this market loss is coming from South Korea where bans and regulations have been scarying many investors out of the market.

What are your guys thoughts. =/
