A small reminder, if anyone cares about it:
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.
But in fact, xbtec has achieved lot of delays with last, non escrowed payments. So 5 btc are a decent minimum for a 100 places sig campaign.
