Interesting, the video ads work for you. For the video ads to work for me I have to connect to a proxy server (e.g school). However I didn't bother connecting to a proxy server when using the app because I didn't want to make the long, somewhat perfect script which already took me a long time to make because the video ads had random placement on buttons (to instantly end video ads use 'VideoPace', you can speed up the video to like 500 times in a file).
This is what the accounts sidebar should look like.
Yes the coins are shared, though they must have not had it like that in an old version and never removed the coins under accounts so its all the same.
You can create google accounts quickly or a lot by using another email as verification or use one phone number if you don't already have one then you can make 3 and use one of those 3 to make another 3 or whatever etc. You can do what I did and go to youtube settings then make like 10 youtube channels per google account, you can get more than 10 with phone number verification however.
Oh and youtube sets a subscribe to channels limit every few hours to a day at about 100 or 200 channels, there is also like a 1,000 or so subscription limit per channel.
