YouTube is a very large video site. If they would get serious competition from another platform then they would adjust very quickly. Main reason why YouTube has been stagnant has been because of low competition. They have been having a monopoly on the video market. But now serious competition is showing up from both a service called jwplayer and DTube! And we will probably see 10 other competitors quickly show up! So now the consumers will in the end be the winners.
But then what tends to happen is that people get adjusted to new levels of freedom fast. And then they want something new and better. We should really be grateful for what YouTube gave us. Steemit is like the child of YouTube. And it will become huge because this is a major paradigm shift! You can't just have 1 video service when world population is moving up to 10 billion. We will probably see hundreds pop up.
I really do hope Steemit is scaleable. As in if it will work great with more users too. Because usually things starts to go weird because there is too many humans on a platform and the more people the harder it is to manage properly. But one thing is for sure and that is that blockchain and crypto technology is here to stay. And how it will replace the old ways of doing things.
