The only smart involvement in crypto was to spend a few minutes buying Bitcoin early on and holding on to it. Everything else — all the altcoins, stablecoins, NFTs, large ecosystem of startups, VC funds, DeFi, web3, payment networks, smart contracts, blockchains – has been an immense waste of time and resources.
I disagree. Sort of. I agree that the things you listed like altcoins and stablecoins and NFTs aren't that valuable. Note: I hate using the word "blockchain" to describe these decentralized networks hosting distributed ledgers, but it seem to be the word most people recognize. With that in mind: Bitcoin was a first generation blockchain technology. It's the gold backed standard that supports the rest of the ecosystem…
Developers want to use Postgres, not a distributed ledger. And most end users don't really care about data-sovereignty. If I thought a significant percentage of my app's users did, I would much rather rewrite to conform to ATProto than touch anything on the blockchain.
