For anyone who is panicking at the market-wide price drops, please don't! There is no reason to panic. Look long-term, don't look at price charts over the last week or month, look at them over the last year and see the pattern of rises followed by pullbacks... but the course is always upwards.
If you're new and bought in during December and now see huge losses... the worst thing you can do is sell now. Prices will increase in the long term. The current dip is just a correction to the wild excesses of last month. Don't panic!
If the prices you can see now are lower than the prices that you bought in at, then the best thing you can do is buy more. Why? This will lower your average entry price.
If you bought bitcoin at $16000 and see it now at $8000, the course of action is clear: buy the same amount at $8000, and your average entry point is no longer $16000, it's (16000+8000)/2=$12000.
Don't sell, buy!
Yes I have seen the history of bitcoin prices, indeed the price cycle that goes down often occurs in the previous year. I agree with you that now is not the time to panic and sell the coins we have. Currently, my assets have fallen by about 50% and I still hold them firmly, because I'm sure the next few months crypto prices will recover.
