I have been following this and other Raven threads for some time now. Seems to me that Ravenpool and 3i has some shady shit going on. One is stealing coins the other from time to time has pushed the hashrate over 51% on their pool and who knows if they have cheated anyone. I have no proof and I don't care. I have been in this long enough now to know fraud and lies when I see it. The patterns rinse and repeat.
I can say I have been at
minepool.com for some time now and it has been a good experience. I even won one of the March Madness coin give away. Over 500 coins won during the campaign. The operator has made improvements and the coin payouts are like clockwork. Over 6K coins mined there so far and no problems.
