And yes - what about next giveaway? This is first time I heard.
Arvicco is actually paying a pretty fair price. I am buying XRP as well so he is my "competitor" on here but I will say that his prices are very reasonable, especially given current market conditions.
But as pointed out above, the OP is making a very flawed argument. On XRPTrader, they probably sell for 4x of what Bitstamp charges. So does that mean that anyone who sells their XRP for less than XRPTrader is selling for is an "idiot"? Is the guy who runs Bitstamp an idiot for selling for 1/4 of what XRPTrader charges? These are simple concepts that somehow escape you.
