I would guess that it is going to be hard because there aren't enough viewers in other places. If you are famous like ninja, you could go anywhere and make money anyway you want, hell you could start your own business and website and start streaming there and take crypto donations and stake could have its own streaming service that way where gamblers would gamble on stake.

They have the power to do it, they have the fame to do it, developers and designers to build it and they have enough attention from people to find viewers even if it is their own website.

But twitch does bring a lot more new customers and that is what mattered, unfortunately it is not going to exist in a month.
