I didn't lose money on CUB either.
It didn't matter that price went down because the market cap always hovered between $2M-$5M (currently $3M). With CUB it was always the obvious play to say away from the kingdom because the yields on the LPs showed us that we would more than double our money if prices stayed flat. It was shear greed that pushed 70%+ of all CUB into the kingdom, and it still is.
So HBD 12% for the win?
My big problem with this is that we are paying users to horde money in a non-liquid pool.
The real value comes when we actually have an internal market with an AMM and we allocate yield to HIVE/HBD. This actually helps the network. Forking out 12% interest rates is more like handing out a loan that needs to be paid back later. It only works if the 12% is good enough to get outside money to pay attention to us.
