more and more people are realizing 10% interest a month on bitfinex will almost certainly make more than long term btc holding.
At 10%/month (what I've been making at finex), btc would have to be 6000 in 2 years.
In Bitcoin there's no counter party risk though.
Anyway, how on Earth are these leveraged longs holding on for these periods of time while paying these sky-high interest rates? Especially considering interest rates for USD are at record lows in the real world ... It just makes zero chance. I would not be surprised if something shady is going on.
