But also keep in mind that x20 investment oppurtunity! usually come with /20 risk.
I'd half agree with that. If you're buying ETH with such a huge marketcap thinking it could go up x20... then I'd say it could also pose a x20 risk since the coin is already up so much, but something like, ACOIN ($60,000), MILO $(60,000) or even BIOB ($4000) the marketcap is so low that there is way more upside compared to downside. All of those are active coins with working wallets that have super low marketcaps. There really isn't much room to go down and lose. Even fake coins with broken wallets and no support have higher marketcaps than that.
