I look at poloniex " Lending " demand is still quiet. demand borrow quite a lot, but demand that lend absolutely no
I think its risky to keep your btc in these site. because they may scam you one one day, and took all your money.
The thing is that yes we can make a good money from Signature Campaign (High Paying), the trading thing that the op mentioned in the OP thread is risky, because if some one dont know about trading he may loose his btc, because its happened with me that i lost more than 80$.
it is risky indeed, but investing isn't something that's easy and without risk. if i would lend my money with such purpose i would prefer bitfinex. that exchange gives me much more confidence than poloniex.
