Did they credit members on yobit, or are they just trading futures at the moment? I know there were a few sites that were crediting early.
Obviously it's a derivative thing, as BTG hasn't been "launched" yet, so people are straight up gambling right now with something that doesn't exist. Yobit has done this before, and it's sketchy as hell, and I'm wondering if it's even legal. No US exchange would probably get away with just creating a derivative security/currency out of thin air, but this is Yobit. Ny prediction is that they'll eventually get shut down by regulators. I don't even know what country they're based out of.
I don't know whats up on their minds which they can able to make such tradings or moves without being backed up by something. Bitcoin Gold? It doesn't still exist yet but look at how Yobit did able to make an advanced trading on it which I can really consider as shady at all. They do have the power since they ran off the exchange and same as others said here they did this thing before on bitcoin cash.
