My company is KYC'ed with changenow, their license allows them to exchange crypto. you are correct at some point it might raise questions, however, im planning to switch to 1inch solution which is DEX.
I wouldn't say that 1inch is really a Dex exchange, and people won't be able to exchange and swap real Bitcoin but only tokens built on various centralized blockchains.
Maybe you could consider using atomic swaps instead, or use something that is connected with Bisq and other p2p trading platforms.
You don't have to be precise, but if it's not a secret can you tell us how much coins/money got exchanged using PNNV website through ChangeNow?
