FTX was a regulated exchange, so your alternative to crypto currencies is then broken as well, the regulators didn't then do their job, this scammer Sam Bankman-Fried was allowed to create fake money out of thin air and the regulators were not able to stop them.
If you can't follow the mantra "not your keys not your crypto currencies" or if you don't have the technical ability to hold your own keys then don't take part in it.
You let someone else hold your crypto currencies, don't take the time to check if the said people holding your money has any validity and then you lose all your money? it unfortunately is your fault for trusting a scammer, you got duped by a scammer, just because someone can run a Superbowl advert, get main stream media to call them an amazing vegan who's such an amazing role models to us all, or hire a few celebrities to say good about their company doesn't make them someone you can trust.
Crypto currencies and block-chains are still a very young and developing industry, its risky, there are thieves like Sam Bankman-Fried and then there are politicians and other special interest groups who will get in to bed with these scammers and try to take your hard earned money from you. Don't be a victim to this kind of scum.
Crypto currencies and blockchains are here to stay.
