I don't really know the story about Sumokoin and fireice, but if they will come back to the original CN, I will switch to RYO if fireice and psychocrypt are really involved in this "new" coin.
Ryo stays cryptonote-heavy and asic-proof. Fireice_uk and psychocrypt are really involved in this coin as you may see in ANN text.So I guess I could mine with my actual SUMO adress on https://pool.ryo-currency.com ?
Correct.
