0.1. BTC for a full member is damn expensive.
Do they have any potential activity?
How is it damn expensive? Seems to be a pretty standard price around here unless you're a tightwad who likes to lowball. Also looking at your last post you seem to have given a loan of 0.1 and taken a Full Member account as collateral so if it was damn expensive not sure why you would loan the very same amount out.
