I'v got a few accounts with more credits.
The sub credit isn't that good in my eyes, inactive subscribes..
My EV account has barely any credits, so, just out of interest, why are you interested?
And maybe, but when I used to use EV on my old youtube account (Jearedmouse00, had about 20k subs in the end), it did gain a lot of views on a lot of my videos easily, and quicker than I would've without the subscribers. I was also earning a bit of money from youtube too. But youtube being bitches banned my account due to copyright infringement as far as I'm aware, they wouldn't release any further details.
