The market is move to critical situation so coins also hard to choose in this scenario. But standard coins are good to invest on this dip and secured tokens are not possible in this dip.
If you really interested to participate in crypto you may choose Bitcoin because this will be a good investment in current market.
I agree that this might even be the best solution for now. Security tokens depend a lot on the success of the product they represent. And they are contributing to the way of treating cryptos as assets rather than money. I am more into the projects which are at least trying to help people use cryptos to pay for goods and services instead of dumbly trading them. I believe that cryptocurrencies can be a very good replacement of fiat and we as a community should show that we want and support such changes. Trading devaluated the facts of decentralization and cryptography and makes this market a weird alternative to stock 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.
