You're failing to explain that it "supports" THE WORST of "crypto and non-crypto".

1) Irreversible transactions and lack of consumer protection as in "crypto", i.e. you're fucked if something goes wrong since ionomy accepts only BTC/ION and has "Seychelles" in its TOS.
2) Centralized control as in "non-crypto", i.e. you're double-fucked if something goes wrong since you can't take your money and go elsewhere, and the potential of something going wrong is amplified (one screw-up by the team could screw up everyone).

There is a reason why crypto exists the way it does, i.e. irreversible nature of transactions and other features that increase risks are meant to be counterbalanced by the full control everyone has over their own funds, which removes third party risk. If you get rid of that control you get what is essentially an illegal bank with no FDIC or even a bank manager to yell at.
