What can't you understand yak?
Do you know any merchant that holds bitcoins instead of FIAT, even if they accept it ?
If they do, they have lost much money.
uh.... the company that you are talking about for one.........................................................................
By merchant, I mean standard merchant... not a bitcoin specialized company !
A merchant which doesn't handle crypto currencies. Your supermarket. Your electricity re-seller. Etc.
maybe you live in a hole in the ground... or in the past somehow, but if you were to actually follow *ANY* crypto related news you would understand what you are saying is blatantly false.
the world isn't your 2 mile radius where you live. i suggest you look into some of the places in europe where large portions of entire cities businesses are adopting bitcoin (and keeping over 25% of it *IN* bitcoin)
maybe you should think about how paypal will handle bitcoin once its fully adopted into the paypal ecosystem, they will need to keep huge reserves of it.
regardless you seem to have some reading up to do.
