Yes, some day in the future we don't know when but it'll fluctuate less once the price of Bitcoin increases multiple times making it harder to clear buy and sell orders.
I think so, but if bitcoin is really going to be $250.000 after 4 years so in a very short time! these fluctuations are very natural, also with regulations and clarity in the market it will fluctuate less.
Bitcoin reaching $250k after 4 years sounds like a dream.
I think so , if btc going to substitute with existing currencies , its value will fix or fluctuates will be less. and also there is another parameter : amount of btc. as you know it is 21.000.000 pieces.
after all btc be on market this also makes stabilization I think. ( But it is going to take so long time)
There's no way bitcoin is going to replace fiat.The limited supply won't help much with the stability because it mostly depends on the demand.
