NOT YOUR KEY NOT YOUR COIN. No matter the kind of offer Celsius and FTX give, it's not worth handing them over your custody of your coins.
With Bitcoin Spot ETFs are coming, people will be given a new option to invest in Bitcoin.
If they want self custody, they will buy bitcoin directly and store bitcoin by themselves.
If they want convenience and are not fearful of custody, they will not buy bitcoin directly but buy shares of Bitcoin Spot ETF alternatively.
If they choose Bitcoin Spot ETF shares, it's their decision to take risk by spending money but won't actually own bitcoins.
Some people can feel storing bitcoin by themselves is inconvenient but I don't see it like this. I love self custody and see it convenient too.
