After a increase value continuous last year, Bitcoin peaked at $20k and Eth over $1k. The market was expected so much, but throughout almost the beginning of thisyear, the market continuity plummet, now Eth is just over $ 200, so will the market ever return, whether that this is the mark the effect of the collapse (I'm a very confident person in the market), this is just a small discussion, please do not be too important.
No one knows the future and can see if it'll be back or not. What I can advice is if you're really in love with the Blockchain and believe in it, then stick with it. No need asking Everytime if it'll be back. Just invest what you're comfortable losing and generally have fun.
