5 BTC Escrow is still a lot more than other new campaigns have provided. Shouldn't be a problem, good gesture from their side.
XBTec offered higher rates and escrowed less (even if you multiply the escrowed amount by 4, because they only accepted 25 participants), so it should be all good.
That's true, but xbtec's escrow was only for 1 week. So I see what you mean about multiplying by 4. I think you're right, it should probably be enough.
About the rates, it looks like only the full member rate is higher than PD, looks like senior and hero members, the rate is equivalent,right?
