to be honest
if cointerra delivers what they promised and when they promised it's kind of sad how the whole asic bticoin world developed with the shittiest companies being able to commandeer higher prices for shitty products. best companies showing up later to the game

I don't think they are....and that means people can do a chargeback for just about any reason.
