I want to run two 24/7 livestreams at once, both these streams will be on Youtube, is it possible?
I think that will depend on the platform. I don't think YouTube allows that, unless you use two accounts. Either way, the answer is to open two instances of the upstream program (or browser for web based). Your only technical limits are your up speed and processing. Naturally, some platforms specifically block it. If we're working with recorded material, not actual live streams, then any consumer grade laptop should work.
