I doubt anyone will send you his "bitcoins now" without escrow. Are you ready to do it the other way around? Transfer ownership of your ICO account and email first, get the bitcoins later? I thought so.
Firstly according to Sasha in the slack you can't transfer ICO accounts as you can't change the email address assigned to it. It is my personal email which I have had for many years, the content inside it is important and is linked to every service I use.
Secondly even if I could it has my personal twitter, facebook, email and other details on it so I would not be comfortable doing that.
Thirdly I'm not selling the entirety of my ICO funds. I'm simply reducing my risk and taking some profit, not that I should have to explain myself to you.
If you can show proof you're trusted, offer discounted prices and be the lowest sell offer people
believe it or not may decide it worth while to risk without escrow, especially for lower volumes. I'm not saying they should but if both parties are happy with the arrangement who are you to stop them.
