If you really interested to participate in crypto you may choose Bitcoin because this will be a good investment in current market.
I'm not sure how realistic it is to hope that crypto will be looked to more as cash than investments. With such a volatile market, not many people would even want to try using crypto as money. On the other had, security tokens offer tokenized real-world assets, which may touch on the fundamentals you're trying to reach - meaningful, tangible impacts on the world. If I were to invest in a security token like Corl, I'd be investing in the funding of startups and I would not be blindly trading them.
