Just wanna say that I had a decent amount of PS<>BTC trades (avg $100 I think) with Planetist for more than a year. Last time (1-2 weeks ago?) I also sent first (for $50 if I remember correctly), mostly because we read each other's PM slow that time and I personally did/do trust him.

Still I never vouch (as in "guarantee") on principal and I personally don't escrow, but just sharing my good trading experiences with him and saying I do trust Planetist myself.
