That is a big mistake, investing when the bull run starts is a wrong move, you need to buy when the bear trend is on. Of course I would only buy bitcoin and not altcoins or the hyped projects that are running in the name of altcoins.

Just because something is hyped does not mean it is a long term value project. Rather it indicates that the project is a short term one and the cheap thrills are the only thing worth getting from it. If you are into joining ratraces which may crash when you sleep, by all means get into them. But bitcoin is evergreen decentralized and censorship-resistant, you can never go wrong with it.

Next year some new hype will start and these will die out, imagine that happening right after you invest >10% of your assets into such tokens. You are going to go rekt and you will realize it too late.
