..or use their heads and pay in flat which varies very little and removes that problem as a few others. Is there any benefit in paying for a pre-order miner in BTC at all? No protection, massive swings in exchange rates...two of the reasons it's hardly used mainstream never mind on stuff like this.
Why do we mine for Bitcoin again? Can someone remind me please? Because the above post makes it sound quite worthless! Lol.
I don't mine for Bitcoin to spank on pre-orders by untrustable unknown entities such as we have all seen in the ASIC game, I mine because I believe in the underlying concept of the currency's which I intend to exchange one day with parties I do trust. Pre-orders with BTC have consistently lead to abuse.
