My stocks are doing good enough for me to not care at all about crypto since then. Even if that wouldn't be the case, I wouldn't invest in something that I don't think has a viable path.
Eg. The current solutions are using off-chain centralized transactions to fix core things ( eg. transaction fee).
Also flash loans don't take anything out of your wallet/account either and I know of people whose bank accounts have been hacked.
There's plenty to complain about btc but you've somehow chosen the least convincing argument for why you are a noncoiner.
This one recent example of an crypto exchange that fled with the money, has defrauded more in value than the entire ACH payment system worth ~51T ( fraud = 0,0008 % = 0,08 basis points).

We poor old salty nocoiners can only wipe our flowing tears with the 100$ rags from our fat wallets. Oh poor us, we foolishly put our wealth into cashflow producing assets. Oh the sorrow every quarter as the dividends are deposited in our flash-loan-hack-proof bank accounts.
