What will happen if people just stop buying bitcoin? Will bitcoin be as usable as now Or will it be a step towards the end?
How will the market value react to it, people wanting to sell bitcoin but there is no one to buy.
If no request of bitcoin will die, because the bitcoin price determinant is the number of requests. but that's unlikely, because bitcoins are needed for global transactions.
If people lose interest in Bitcoin and they stop patronizing it, the price of it will surely go down. In this case, there could be two possible effect, either the demand might also drop down or it also might encourage people to buy because of the price deflation.
