OK, so you put off your buying and now BTC has experienced a fillip and all of the sudden bitmain are greedy?
When BTC was falling, everyone with a keyboard was shouting at bitmain to tag their BTC price to USD so they could buy in fiat, and also asked for fiat outlets e.g Amazon et al, to which they obliged. They went further and offered a 15% discount for a period after setting up the fiat channels.
Still some jombas put off their buying decision. Now the discount is gone, BTC is rising against USD ..... you only have yourselves to blame!
But all we have in this thread now is mourning and whining .... guys, what do you really want? You want to see bitmain go bust?
