A good project will not list its token to a bad exchange no way it's a good coin to invest, Yobit is very notorious for pumping and dumping schemes on all coins traded here not only pump and dump they are also notorious for scamming their traders, just check the scam section and you can see a lot of complaints about Yobit.
Most of the coins that are listed on Yobit are issued by the exchange itself and are not traded anywhere else. SEDO Token, which is a shill OP, is no exception, as it regularly promotes crappy coins that are traded on Yobit on this forum. To do this, it is enough to view in the OP's profile all his threads that were created on Bitcointalk.
