Maybe because a lot of people are autoselling anything on cryptsy, cryptsy don't have such good rate.
I'd happily accept doge, because there are also other exchanges.
whats your favorite exchange for doge?
cryptsy charges
Our fees for market trades are 0.2% for buys and 0.3% for sells.
but as we are always buying one thing and selling another, is that .5%?

so on a charge of 1872.52941176 DOGE for 3 hour rental the fee was 0.000007700 BTC
and i got 0.00255767, so thats about 0.3%!
take that to a day 0.000061568 out of 0.020522
or 0.003 out of every btc. so less than $2 per $600? and how long does it take to get to 1btc?
that isnt too bad for the advantage of giving the customer more ways to pay. Its like taking a visa card! especially as we have been slashing our prices to keep up with the joneses.....
