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.
Everything have two sided factor , at one side you will find that particular thing have at one side benefits but the same thing at another side leads into some side effect .
Here if will consider that you are going through that thing which have not a better option in the future then how we can consider that you are in favour of cryptocurrency , here you are only showing your thinking to have cryptocurrency in general life and that is not a perfect option to use in general ( in your view ) .
But why you are not thinking at another side , that , one day you bought a guitar and after some days you found that you need to pay more amount of btc that what you paid earlier for the same guitar ( because at one side if price of Bitcoin can fall then at another side pump will also take place that will give lots of opportunities to the holders ) .
So it is a matter of time , here we just need to take attention over the positive and good benefits that we can have with cryptocurrency/Bitcoin .
Otherwise if we will be negative then what about the haters .
