500 us is interesting offer if you live in the same country as me..but import tax is expensive here in Indonesia.

I believe that btm is interesting coin...most likely to hold for a year or two..
I cant find much info about other tensority coin, as first of its kind and "controlled" coin,
but B3 might be bad bet (for now)...its about 7 hash rate of 750ti
maybe it should have newer firmware for performance improvement.
