eth is ok, and as for long term investing i also can recommend u uniswap, polkadot and new dex - xsigma
i also think that interesting defi also good for long term hodling; what's the project xsigma? can you share any link or something about this ?
here's it) they are backed by a public company and look credible
Didn't notice before about the project. Anyway, DeFi hype maybe boost any project no matter whether it's real or not. But, stick with real project like ETH, uniswap, polkadot would be game changer in the long term.
