mintpal only adds a new coin every 2 days, and DRK was added today so it won't be added tomorrow
Are you sure about that? I thought it whas once a week?
Yes i am sure, i actually spoke to someone at mintpal via twitter because i was unsure myself at the time. But they said every 2 days they select the top coin from the voting section, and the day in between they choose a coin themselves.. Makes sense because today they added Dark coin, 2 days ago they added TAK, those were both the top voted coins. and yesterday they added LTC which was their selection
