They may, I didn't know that youtube was also banned, but I believe that it depends on the streamer and what they do to get the viewers. Are you telling me that drake could stream "anywhere" and I mean literally anywhere and can't find viewers?
Of course he would be able to find some viewers no matter where he streams, I feel like Eddie could do a smaller version of the same thing, of course not as much as Drake but still find some viewers, and that means it is going to be easy to handle. On the other hand, if we are talking about you or me, then it is going to me hard because we wouldn't get a lot of viewers anywhere, so it depends on their fan base, not where they stream.
Finally Drake will make a stream tomorrow on Twitch just few hours before the ban of Stake will officially starts there. So if they are rushing to put in place a stream now and announcing it only one day before, it's certainly because they want to make a last stream on Twitch. What is the reason if it's not because they think themselves they won't get the same success on another streaming platform?
Tomorrow Drake will stream at 1am GMT, we will see what will be their next move. Probably Dlive will be announced for next stream due to obvious changes, Twitch is no more priority for gamblers after recent changes. Drake has huge audience, the new announcement of Drake vs Stake will be huge for gambling streaming world, IMHO.
