While i agree that this is not really a crash as much as a long overdue correction, i have to respectfully disagree with your point about cryptos being little more than a ponzi scheme. Unfortunately the ones that have been getting most attention (Bitcoin, Doge, Ether) have been a poor representation of what the crypto space has been brewing thse past couple of years. I would highly recommend looking into DeFi projects such as AAVE or maybe a better representation of whats possible with Smart contracta on Cardano or Solana. There are a lot of "shitcoins" but there are also a few innovative gems that are going to make a major difference over the next decade imo.
