Cardano needs its own official ‘exchange’

Cardano needs its own official ‘exchange’. Where the trading of $€£/ada is possible to a bank account.
I think that would be a game changer.

Cardano has defi.
But it is not possible to trade ada/$€£ in to a bank account without relying on a centralised exchange such as (binance/kraken/robinhood etc).

If exchanges delist or stop the trading for whatever arbitrary reason, then ada ends up as an isolated currency, and I don’t see many people/companies accepting ada as payment for groceries and rent payments.

I would love to discuss a solution for this. Maybe there is something in the pipeline already?
