We often earn money from youtube channel by showing ads from adsense and suppose if someone want to earn bitcoin by showing ads on their youtube videos then is there any alternative ad network which provide ads for youtube channel?
Yes, You can.
You just have to cash out all of your ad sense earning directly to an exchange so, you can convert in Bitcoins, And I don't think that YouTube or google will add Bitcoins as payment option if it happens, Bitcoin will rock the world.
Correct I own the channel but the payments are not in the form of bitcoin. In the monthly payment dashboard and payment also been added as USD alone not other currencies too.
Most of the people doesn't know that earn money in YouTube which is better source like bitcoin which can give money easily with the ideal works in videos.
