who knows DLive will catch up on Twitch in the future? as Twitch is banning most gambling streamers, they will go to the next good one. and later on, DLive platform will improve further to cater high number of viewers. we can't say yet the future of DLive at the moment but this early, they are already showing good signs that they can handle high number of viewers.
I don't think they should be even compared. Twitch is way more mature and knows their target audience. On the other hand i still don't know what kind of place DLive will be in 5 years, it's still kind of all over the map and it has 1.8 stars in appstore with only 4K Ratings.
I am pretty sure twitch keeps ruling with live streams as it already has an edge as a leader, at least with online gaming. Gambling on the other hand can be tricky to broadcast without decentralized service like DLive as there are ton of games that aren't licensed in United States.
