If majority of the people will used the bitcoin in transaction. We can assure and prove to other people that bitcoin is really the fastest way to transact especially in buisness. Not just that ,the value of bitcoin can increase dramatically in less than a minute. It just need proper managing .
First question is why would people use bitcoin in transaction? Bitcoin is not fastest way, and bitcoin price has nothing with selling goods, they have their own price and that price doesn`t depend from bitcoin. Second question is what you think what kind of managing do we need?
Local business need legality and stability, what is someone sell all store for bitcoins and the next day bitcoin price drops significantly, merchant will lose a lot, and he will lose business cause he will not be able to order new stuff. I think local businesses need stability, they will not risk their money and wealth just like that.
Merchants don't need to keep bitcoin if they don't wish to expose themselves to the volatility of the market they could always sell their coins immediately after getting a purchase.
Yes, in theory that should work but I also think that it also depends a lot on the size of the merchants and the volume they handle, to cite an example, let's suppose that a large merchant sells ten thousand usb when price BTC is on $900, if the price falls that same day $50 then he will suffer a loss according to the number he has sold and paid him with BTC, and it's what you mention he should have sold immediately, but what if his sales were made in 20 hours almost all day, talking about an online store for example, the seller can not be changing his BTC every moment,so it could have to wait for at least one day to make the change, but do not know if the price will go up or down, it went up more than $900, He will be happy and will do the exchange, but what happens in the opposite case, that is to say that the price goes down, He will have to wait until the price recovers in the best of cases or sell at a loss which would be very bad for the business, and here you start to see why not many businesses still accept it as payment.
