That is kind of the way i see that agreement . Absolutely enforceable unless it is ruled out by a court or any part of it .
The part I object to as a cash buyer is the attorney fee part . What if they did not pay or something else went wrong to stop payment . Then you would have to go to arbitration as you agreed and would therefore have to pay their attorney fees . That is just not right .
 I think this agreement was actually made up for bitcoin buyers . They seem to think they should be paid back more coin then they gave up because the price of coin has dropped . Well that is the gamble they took when they used bitcoin knowing it could drop in an instant . If you gave 3 coins you get back 3 coins just as if 3 100 dollar bills you would get back 3 bills . That is the disagreement that makes this form go to bitcoin buyers . As such I see no need for a cash buyer to be subjected to this form as there is absolutely no disagreement on cash as long as the refund takes place . I also would not sign it if I used bitcoin .
