Heya, I'm just curious, is there any reason why you're not using exchange platforms? There are many reputable ones out there that support instant transactions and usually its very rapid also. I usually prefer using them over finding random people which of course you'd need to trust them with your money, and sometimes an escrow could be arranged.

For me going down this route its much more complex rather than doing it over exchanges where at least the different platforms have been verified and there will be no need for an escrow or other checks.
