Cryptocurrency is not an abject disaster.<p>Drew is right that proof of work mining is expensive and has serious negative externalities.<p>Drew is also right that cryptocurrency, via its growth, hype, and decentralized and self-sovereign nature, is often an ideal vehicle for certain kinds of criminal activity, including pump-and-dump fraud or ransomware.<p>Drew is right (perhaps indirectly) that many or most well-meaning crypto projects will end up losing money for most of their investors.<p>But, there's a lot more going on in crypto. At this point, if you think crypto is wholesale a scam, bad for the world, or a fad, you're simply misinformed.<p>As Drew observes, Bitcoin has a cost problem. For that reason, many crypto insiders think that BTC's reign as the #1 top crypto will come to an end within a few years.<p>More reading on Bitcoin's cost problem <a href="https://twitter.com/RyanBerckmans/status/1386505715938775044" rel="nofollow">https://twitter.com/RyanBerckmans/status/1386505715938775044</a><p>In contrast to Bitcoin, the Ethereum community is actually building many useful things and will soon stop proof of work mining, replacing it with proof of stake. As a result, Ethereum earns enough actual revenue that ETH is expected to generate lots of cash, like a Buffet stock, in the coming decade.<p>Today, much of Ethereum's revenue is what we may call "reflexive" or insular, in that the revenue is related to cryptocurrency services or speculation. That might make Ethereum's apps appear to be "not useful" or "scams". However, I think it'd be a mistake to conclude that just because most early Ethereum apps are related to crypto, that they'll all be. Ethereum apps are increasingly connecting with the regular economy, and that's the primary growth opportunity.<p>Further reading on Ethereum's cash flow <a href="https://ethereumcashflow.com" rel="nofollow">https://ethereumcashflow.com</a><p>Disclosure: I hold ETH and no BTC, and am the author of both links.
