Its truly hard to understand the Bitcoin market. It's not like any other monetary market. The demand to borrow in bitcoin comes mostly for transactions which can not be handle through cash (drugs, etc.)..and the people who perform these transactions don't care for how much interest they have to pay! From 50,000 feet above the ground, it seems like some pyramid scheme, but once you understand the demand for bitcoin and its sources, it seems justified..I am not an expert..but I am an investor like you and others. Bitcoin still evolving and I don't think anyone can say where its headed.
