When they see extra profit could be made by accepting Bitcoin.
But I don't see it happening as they only accept regulated payment methods.
And then you have refunds, that will be hard to issue when the rate fluctuates a lot.
 

Actually, there are some online store already start to accept bitcoin and I think it is a good news to all bitcoin users because they could buy the things that they want in some easy payment. In addition to that, using bitcoin as a payment is a nice idea and it is quite convinient because you can pay your bills instantly.

It is nice to imagine that Youtube and other websites will start paying us with bitcoin. But I think that until bitcoin is not regularized, I don't think they will start transacting with bitcoin. This is both for their protection and as a bind to partnerships to other payment options if they have any.

soon, i believe youtube and other major sites will be using bitcoins as a payment method on the future because bitcoins is definitely the best and the most popular payment tool online better than others (excluding paypal)  because its easy (not so), fast ( not so), anonymous (not totally). for sure they are aware of it and they are now realizing it that bitcoin can add innovation to their current system and they might want to be left behind on the latest trend online.

Actually there are no possibility to pay Youtube by via Bitcoin it's my personal thinking.I heard through my friend may be Amazon attempt added BTC payment system after few months.I don't know clear news.

what happen? it will make big changes in digital currencies, especially on cryptocurrencies sector, id youtubea and the big company use bitcoin as the payment online, it will make bitcoin is more valueable than other coin or money. it will increases the price

Online payments via bitcoins are quiet fast, easy and secure.
But it not possible for everyone, for that bitcoin must be legal in your country, you must have mobile wallet and internet connection.
The other party must ready to accept payments via bitcoin.
Payments of bitcoins become worldwide only when world leading enter pruners will start accepting it.

Dont think it is coming soon. No one wants to spend his bitcoin today. All everyonw wants is to save it and see it growing. I highly doubt that this time is coming soon. Only when bitcoin's price stablizes a bit you can expect people paying in btc.

Those type of services will not happen until Bitcoin is out of it's store of value stage. Right now Bitcoin is best used as a store of value, but once it scales some more and allows for more people and transactions on the network, as well as it becoming more scarce, we will see the price reach it's full potential (because a lot of wealth be transferred from FIAT and gold) and people will start to use it for payments.

I think you should improve your English if you want to join this world dude ). Although make payment via Bitcoin is very convinient and fast but there are only few shop or online store that accept Bitcoin for payment cause Bitcoin isn't new to us but there are still a lot of people don't know about it and the most important thing is that it's not legalized worldwide so there are no banks are supporting for Bitcoin so with youtube and some other business kind we still can't receive money via Bitcoin
