I don't you can compare with One Coin as that was an outright fraud. Some people have bought a load of HBD to earn interest on it, but there may not be enough on the market to satisfy demand.
I would be great to have more options to exchange it, but when we lack those then may get shafted on price. I still think the Blocktrades people are committed to Hive. It's in their interest for it to do well. I just don't see many other places where anyone can earn crypto like this even if they have nothing to invest but time.
