Yah. Everything could be a scam, even long lasting businesses could regardless of how legit they were at the start. It's just more prevalent in crypto since a lot of people are new to it, or are beginners in terms of understanding what and what is not a scam, so it's much more obvious. I don't have any faith in the crypto world, I have faith in the fact that my Bitcoin are safe in my hardware wallet instead.

I'd honestly avoid crypto to put your wealth in, it's volatile, risky, it's an investment that you go to when you're ready to lose whatever you put in. There's probably a lot more other investments out there that are relatively safer. Ofc profits drop off but that's the payment for being safer compared to crypto.
