Long time ago I remember reading about some service, that allows using single use credit cards. Last year I was looking for it, as many services cannot ne trusted with this information. But I could nothing like it. Maybe I was just dreaming...

Getting a legit card like that could be possible, but I don't think its worth of hassle and possible costs. Some companies practically throw these cards on you, but usually there is a catch.

You might be thinking of Privacy [0].

Capital One has an app called Eno which generates alternate card numbers, but they are still tied to the same account and identity.

My capital one card has virtual cards, and I’ve seen it other places. The only issue is that it’s done by a browser add on that has incredibly high permissions. I handle it by using a separate Firefox profile for the rare occasions I need to use them. I start Firefox with that profile, use it, then go back into my normal profile.

Revolut has disposable virtual cards - https://www.revolut.com/help/making-payments/getting-a-card/...

It's not about the limit, but about the tying of identity. If you enter a CC number, Google will then be able to know exactly who viewed the video. If you use youtube-dl, or even ad-blocking, who knows if that violates some T&C, and they could then shut down all accounts connected to you...

I’d use a temp card from privacy.com or something.

That's naive, they will eventually block those kind of virtual cards just like they block virtual phone numbers. The point is to tie the account to a real identity.
