Nobody forces you to use Binance or FTX. I have been using Bitcoin for 10 years and I've always stored more 90% of my BTC in my own self-custody wallet, only used exchanges briefly.
In addition to that I now and then try to pay with Bitcoins at other stores. Last time got excited about boltcards (https://github.com/boltcard/boltcard) there are few places in my country which accept it, but it is quite a new thing.
Meanwhile the local authorities don't know what most of those words mean.
