There are, absolutely, crypto Ponzi schemes. (And stablecoins are largely such things) However there are also valid uses of crypto/Defi. I've used them myself to send funds easily. They are enabling truly symmetrically fair exchanges etc.
If you don't like crypto, don't buy it, don't mine it. Following eth 2.0 the energy usage will be minimal and it won't be harming you. Preserving positive freedoms generally and avoiding negative freedoms (constraints on others) is a good thing imo.
