How about PRT/BTC on CoinMarket.io?
It would be quite slow to deposit, considering a 100 confirmation requirement...
(a hint to the coin's dev: the 100 confirmation requirement is ridiculous when you have enough hashrate (eg. not a dead coin))
we've been waiting for this day to come!
I think people can live with the 100 confirmation for now. It's only really 25 mins which is lower than a lot of coins already.
