I know this is off topic.  Sorry, not sorry.  Everyone seems to brag about Canaan vs Bitmain so I want to try the new 721 out.  I ordered it and then was told I couldn't pay with Bitcoin.  How can Canaan not accept bitcoin for purchase of there miners?!  Just had to pay a $100 wire fee.  WTF!  Sorry just had to vent and this board seems to have a larger amount of sensible people than others.
