I think that now the best option is to buy blockchain tokens, since this is where all the capital flows.
Are there cryptocurrencies that are not blockchain tokens? Or do you mean to say those projects that have their own networks or blockchain where other projects can build on their own?
In addition, there are large sums of money for development, and we have already seen that they hold up well despite the fall of the market. Personally, I prefer NEAR ATOM
Those are good projects that you've mentioned and if you think that you need to have huge money for development. Let those projects fund for themselves since they're also going to be huge once the community started investing on them.
