I asked another poster who mentioned an OTC desk so I’ll ask here to. I have functionally no experience with crypto but am pretty well versed in traditional fx. The amount the op mentioned would be quite hard to trade otc unless you were doing it frequently (read daily) with a fx partner. It’s just too small an amount.

It’s almost exactly the use case you want for an exchange (or really in fx a consumer liquidity platform as they aren’t really traditional exchanges).

Is that different in the crypto world? If so why? All of the costs (ie risk management) seem more expensive in crypto than fiat.
