What benefit is there from selling XRP on crypto exchanges?
I know there are concepts such as gateways and such, and I know that having XRP on Bittrex or Poloniex "creates liquidity", but how does that help XRP in any way? No bank is going to buy USDT or BTC, and then sell it on Bittrex for XRP, then send it to another bank who will then perform those steps in reverse. So how does selling XRP to speculators to trade back and forth help XRPs case?
To me it seems like cryptocurrency speculators (i.e. traders) and banks will exist in separate silos.
