Why Twetch will win?
Older technology will be superseded by a newer technology if the new technology offers new features that are cheaper, faster, and/or better than the old.
Being cheaper and faster may not be the killer features to replace an entrench system but additional features that are useful and indispensable will. Monetisation on Twetch is this additional feature.
For Twitter, trolling is toxic. It kills user experience. Trolling is endemic because it is free. Putting an economic cost. even a fraction of a cent will bring the worst effects of trolling under control. Trolls cannot commercialise their business model on Twetch because it will be too expensive.
Putting your money where your mouth is. How true! When you have to put your money where your mouth is - You trend towards truth and honesty. Doing otherwise will cost you money.
