I leave the market or disappear as you say weak projects. projects that failed to develop their product or for example those who could not interest investors.
Although there are examples when due to the strong market dips (as it is now), both strong and promising projects disappear and disappear ... this is very annoying.
Unfortunately, the weak leave the market, and the strong remain afloat. Shitty coins come out, fall in price to the floor, and only companies that have a lively and promising idea are in balance. The fall of Bitcoin is a temporary phenomenon that may soon turn around or fall even lower. And only promising coins can survive in this market.
In such difficult times, when even Bitcoin and Ethereum dog down, I think it is best not to invest. For half a day I lost 200 dollars only on Ethereum. But I do not withdraw yet
