What are some of your thoughts / ideas ?
Firstly, do no harm. If I understand this correctly, right now to earn extra points for voting you needed to participate. Allowing bitcoins to purchase points would allow someone to buy their own rank (rather than rank being based on popularity / merit as it is now).
So as a result I don't know that bitcoin and YouNow points should be convertible between each other. Additionally, since points are earned from participation -- you'll see bots trying to earn points by creating fake accounts and posting synthetic comments, and then the bot owner spending those points on a controlled account/performance.
Perhaps one method that would be useful would be for YouNow to add the ability to accept donations (in bitcoin) for the performer (or show the performer's bitcoin address so that YouNow isn't in the middle).
Perhaps there is room for a version of the site just for "Pros" -- in which there aren't points but instead just currency units used for voting.
This also gives me an opportunity to describe a killer idea that I had. Add in a wagering component. There is a place for some type of in-site investment model where a performer's "stock" is IPO'd, where investors can get their money back (or profit even) by speculating on that performer's eventual success on the site. This is quite a tangent from what YouNow offers but I wanted to show how there are related concepts where Bitcoin might become very useful.
