What's the cause of selling pressure, Mastercard?

I just thought of a new fun way for you Bitcoiners to lose money. It goes like this:
1. Buy some BTC with your CC on Circle.
2. Fund a CC with BTC through one of jonoiv's "100's [sic] of bitcoin card services."
3. Use that CC to buy more BTC on Circle.
4. ? ? ?
5. PROFIT!
people that use pre-bitcoin fueled credit cards usually get their bitcoins in other way than buying them with credit cards. Kind of obvious, not.
By the way, why so much hate against Bitcoiners?
