What we knew/know as Sumokoin is now branded as Ryo under the lead of fireice_uk. The new Sumokoin is a hardfork back to Cryptonight Classic, thats why the hashrate went up by factor 10. This team consists of Quang Vu from the old Sumokoin team who also was Sumoshi and two others, as he admitted. So he was rather economical with the truth all the time, from the beginning. A liar will not be believed even when he might speak the truth, that's why I believe the version of fireice, even if I think that the way he took over the coin was not that friendly. Who knows what happened in the background.

Bad thing is: that SUMO seemed really promosing, but I have to admit that lots of stuff looked to be faked or not 100% true.
Good thing is: all SUMO holders now have the same amount of RYO - it has to be seen what this will be worth...
