And then they also have the additional risk of losing value(If BTC were to drop).

Perhaps but this would bring large amounts of credibility and publicity to bitcoin increasing the amount of new buyers...
I'm no expert though

It would bring attention
But bitcoin is already being pumped all day everyday on CNBC
A lot of big money is already in that's why we are up 800% in last year, Amazon will never expect bitcoin. They won't risk there government subsidies just to please a few thousand customers. If they did they wouldn't expect bitcoin they would be paid in government currency and sell the bitcoin through bitpay. This won't help bitcoin long term in anyway.

Being able to use bitcoin in more practical ways won't help it long term? Again im kind of a newbie to this space so I've got a lot to learn.

Now I know this is probably a stupid sounding question but can you explain to me why the government would cut subsidies to amazon if they accepted bitcoin?
