TUBE coins are coins you earn just for being online.
You install their ad blocker and they keep track of your time online. It started as Bit.Tube and they paid you TUBE coins just for watching/posting videos. This model was named "airtime" and they carried it over to the entire internet. Coin is tradable on a few different exchanges already.
In future you will be able to stake coins and make passive income. For instance there is a limit to how many hours per day you can earn TUBE for internet time, staking will allow you to increase this.
If you stake enough you will get your own node and can host other people's channels on it. New channels will be limited to short videos but if they can find people to host they can make longer and longer videos. Node owners will get a percent of the coins earned by videos they host.
Installing the extension allows you to send or recieve TUBE via your social media accounts

People keep talking about will Facebook ever have crypto, but they already have TUBE. You can also monetize your exisiting social media by linking it to TUBE. When other TUBE users view your profile, you make TUBE. I thought a system of social media monetization would be bigger news.
They have their own social media site in the works, one vote per account instead stake weighted votes. In my opinion they could replace BAT coins, Youtube, Paypal, Facebook and this site. Low transaction fees, and fast confirmations. No start up cost, no buying an account, just install and start making TUBE.
