Pick something you can actually trust, and hold. The people that successfully guess which meme or shitcoin is going to moon are few and far between, and those that continue to win are fewer. It's basically gambling if you don't actually pick a trustworthy coin and stick with it. Every year since I got into it, things have cemented just a bit more. There's going to be a massive thinning in the coming years, but no one knows just how long the timespan will be. For now, the market is somewhat random; great projects can go ignored for years, then suddenly explode, only to fall when BTC falls, having to start all over.
I don't talk to many people about it anymore, because it's all a risk, but if you're going to be in it, you should be looking at 5-10 years, not trying to penny and dime day trade, because you will have losses that way. Trusting anything you see online about crypto in regards to making a quick buck, or a 10x, or anything stupid like that is just people trying to artificially create a moon. Truth be told, no one knows what's going to happen with any coin, best we can do is an educated guess.
