I don't know wheere the ponzi scheme is in Smart contracts, decentralized identities, arbitrary data communication across and decentralized network, ZK-rollups, SK-Snarks, Automatic liquidation, leverage, and minting using other assets as an algorithmic backing, liquid staking, no loss lottery's, loaned crowdloans, algorithmic stablecoins, arbitrage based enabled trading platforms, decentralized incentived storage networks and a million other things. Seems like we are going into another crypto winter :) Every-time this happens, i slowly invest in all the projects i think are promising, then the next bitcoin halving us crypto nerds have 5-10 things to add to the list of 'Interesting things crypto can do', no one understands them so they are easily dismissed and people say "Well i still can't buy an apple with my btc' so thus all crypto has failed.
