I've had the Bittube extension installed for a few weeks and it seems like a very cool idea to earn a bit more crypto just for doing normal browsing activities. I was able to get 5 tubes when I joined and I know had an issue where I had to validate my phone number. Since then I should have been able to earn something, but I haven't earned anything after all that time. I'm not sure what else needs to be done so I'm kind of stuck.
I have tried to check out the FAQs on their site and I wasn't able to see what else could be done to fix it. I still think it's a great concept and I've seen others earn from it. I will keep searching to see how I can fix it, but right now there is not really any earning potential for me right now. I will update you when I fix this and start earning.
