Everyone holding Reddcoin is waiting on ReddID. But we all know they should have released it months ago. The team is having a lot of difficulties... hopefully they'll come to release it soon. It will most definitely cause a price bump.
But as you said, I don't think other big platforms will make ReddID integration possible. We'll see. Hopefully they will though...
They don't have to, and I think it's unreasonable to expect that even from the founders. They may have made a strategy mistake if their only goal is to reach Youtube. They should look for smaller communities that can adopt it first and grow organically from there. Then maybe it will attract the attention of Youtube and so on.
Until that happens, you've probably heard the expression "buy the rumors, sell the news."
