Lets assume bitcoin makes it through all the barriers and survives the rules and regulations of the governments and yet is decentralized.
It is widely adopted and many people have started to use it. Bitcoin has grown to thousands/millions of dollars in price causing huge volatility.
If there are so many people using it on a daily basis, won't the volatility cause huge fluctuations in it's price ?
If bitcoin has such huge volatility how will it be able to sustain it's price ? The fluctuations in price will cause problems to merchants.
So according to what I think, if there is not a solution to volatility then BTC cannot be used on a regular basis for payments in various places of the world.
Eg: One day I go and check a guitar's price about $100 and then a week later I go to purchase it just to notice that I would have to pay more BTC this time just because of the drop in bitcoin's price.
Assuming that each person acts independently, more adoption lowers volatility.
Imagine that a person claps their hands each time they perform an action that affects Bitcoin. If there are 1, or 10, or even 100 people, then you will hear each clap. However, you cannot hear individual claps if there are a million people. You can only hear white noise.
