I am bothered about this issue, lets say you want to buy stuff and you pay in bitcoin, how about the price of the commodity price being reduced for a bitcoin user who wants to pay with bitcoin because sooner or later, the price of bitcoin is going to be double the initial amount paid by buyer. So is there a way anything can be done about this issue.
There is no issue and there is no guarantee that the price will rise.
If you are worried that the price of the bitcoins will rise after you spend them, just buy more.
If you are worried that the price will fall after receiving bitcoins, just sell them.
Issue solved.
