Like many others, I myself also made a huge loss in this recent BTC crash.
you will only have losses if you sell your coins, imagine that you bought when the price was 50,000$, so at the moment you bought you had to have already considered the money invested as something that you could lose at any moment, with that thought in your head everything what you would need to do and be patient and not sell at a loss and wait (even if it takes centuries) that one day the price will be above 50,000$, while you wait for the price to recover you can buy bitcoin with each price drop, that way in At the end of the day you will be profiting and you can even recover your loss very soon. nothing is lost, you don't have to go into depression, you just need to believe and you have to use your head
it also contains losses when someone buys bitcoin at $50k but doesn't sell it at $60k, as the market price of bitcoin keeps fluctuating due to volatility, we all want our investment or portfolio to increase over time not the other way around, because it's better to sell bitcoin at that price higher and buy back at the lower price as the current price at $20k.
but for numerous people who miss taking advantage of the bitcoin price that has plummeted, yes it is better to hold on to what you have, don't sell it at loss.
