Yes I also agree that all the other online website must start paying Bitcoins instead of cash and I think that will happen in some time frame

 How is going popularity of btc I think many website will thinking to payout with bitcoin in online. It will be great decision if it will be taken by online based market .

I would like to ask Are you earning with youtube or your website? now i'm earning with youtube and it is my primary income. Myself will not choose to receive payment by bitcoin. Reason:
First: the price of bitcoin is unstable, example: i always receive my payment on 21 to 23 of every month after i receive my payment if bitcoin is increase then so great but if it is down i will lost my money so i only receive by cash.
Second: if you receive your money that you will not spend then you should choose bitcoin. if you need money to pay to your bill the why you have choose bitcoin to lost more fees for exchange site

not in the near future,if this thing happen what would be the function of MONETARY?if everything in the world will be bought or payed by bitcoins or other coins,then government must abolish the currencies and let bitcoin circulate the worlds need..

YouTube coming up with such plans of paying in bitcoin won't happen in the near future. Already several websites have started accepting bitcoin as an online payment. Little by little can expect more such stores to accept bitcoin which can help in the growth of value.

The time when we come other websites pay as a bitcoin. We need to know all people that bitcoin is trusted and bitcoins will be the new currency specially in online activities.

Youtube is a big company so they will not accept bitcoin until this become legal in all over the world.

Bitcoin will have to receive acknowledgement as a global currency for it to be used as a payment option on these mainstream

sites. I have already seen people posting their Bitcoin address for "donations" ...but Youtube will not pay you with bitcoins

directly. The advertisers are also not paying Youtube with bitcoins, so that also needs to change.  

It's not going to happen anytime soon, I believe. Like with us small players, I'm sure it makes much more financial sense for companies like Google to HODL their coins, if they have any, rather than spend it. I would also imagine that having two pay out options rather than just one would complicate their standard operating procedures. Conversion between currencies, Bitcoin included, incurs fees after all. If they start paying with Bitcoin, it's extremely likely they'll abandon the USD option, and will only be paying in Bitcoin. That makes this scenario even further removed from reality.
