I have not understood most of that article (optifi, mainnet, solana, PDAs, deployer address, program, tvl, ...what?) but what I get from it is that people who run crypto-anything make costly mistakes.

Funny that people still ask me "hey, why do you trust those evil banks? you should do all in crypto instead!" and then laugh at me when I tell them I trust banks more than some random dev on the internet...
