the price of byteball will be the same in dollars or bitcoins. it doesn't make any difference. the btc/usd exchange rate sets the price of byteball too because byteball is priced in btc.

so if the place you're talking about is charging 200 bucks more all you're doing is giving them 200 bucks. you have hundreds of options to buy bitcoin and then buy byteball. it sounds like these guys are price gouging for the honor of buying it directly in dollars.

the only reason it's like that is because of their blatant profiteering. a real market rate would be no different in bitcoin or dollars.

and i've just checked the price there. it's actually over 30% more than the market rate. screw them and screw that. buy bitcoin at coinbase or wherever and go to bittrex.
