Hi, i understand your concerns right now beacuase i'm in cryptos too, and i have not been trading them for long (about 3 months), but i have been doing hours of research on them daily and what i can tell you is that this has been happening for at least the last 4 years every January, and it tends to end after the Chinese new year, which is on the 16th of Feb.. From what i gathered Chinese people control 80% of the crypto market and they start withdrawing at the start of January for some reason or another, and then put the money back after their new year celebrations are over. Another thing i learned is always buy on dips, not when the value is going up.. Hope this makes you feel a little bit better :)
