Many people buy a bunch of altcoins simply because they haven't gone up yet, thinking they will eventually rise, but this is a flawed way of thinking.

If a coin isn't moving, it usually means there's insufficient demand for it.
The crypto market has changed dramatically. There are now millions of altcoins. The best approach is to invest in coins where capital is actually flowing into. When you see the market weakening, withdraw your funds and rotate into stronger projects.
Capital rotation is key, and this will help you survive. Altcoins will continue to struggle like this. Even Ethereum, the second-largest token, is struggling, trading at 2021 levels.
Stop dreaming. Don't buy coins simply out of hope. Only buy when you have a solid reason to do so. If you don't, don't buy.
