People should be aware what type of coin they are investing on. Established coins are going to get back to their all time high however the market is. Buying low and selling high would work with these coins while some coins are such that they rise high for a moment and never get back to Same hype, some meme coins and DEFIs coins are an example of those.
Projects that really have usages and have a set of developers who are not stopping in developing are mostly the good one for investment, it's true that there are many assets that intend to be pump and dump and if you invest to that kind of project and you are not good in selling it in the right timing, you'll just going to waste your money.
I won't comeback as the developers are already enjoying your money after they runaway, most of the time they are going back to promote new project under new system and will do the same thing as long as there are investors who are willing to support them. Be very vigilant and careful in choosing your investment.
