Please add BTC as possible payment in getfaircoin. I was suprise to not found BTC there! Or faircoin in shapeshift.io would be great.
My estimation is that BTC is not there as a payment option on purpose.
Otherwise it would be too easy for people to sell FAIR on Bittrex and then buy them back for BTC on Getfaircoin.
That way Getfaircoin would always be the indicator of the current FAIR price level, instead of Bittrex determining the price and Getfaircoin lagging behind a bit.
And especially when Enric is resupplying Getfaircoin from Bittrex, this will be a bad option, because then FairCoop will loose money all the time and all the speculators will be gaining it.
I agree that something is not completely "economic" about this setup, but I also cannot think of a better alternative at this time.
