As we can see now everyone/every developed nation is moving towards digital currency. In your opinion how much time is required for digital currency to take over the current/existing market or it is impossible that digitisation will never be successful. If yes what are those factors ? In my opinion those countries which are not accepting digital currency, are doing wrong. They are only thinking about the tax. They are saying that we will not get any tax and digital currencies are fake. Fraud is very easy in digital world (that is true but it also happen in every market). Although when someone is doing business in digital currency then that person is bringing money to country that is beneficial for the country...
Your every point in favour of the cryptocurrency is right , but here a big factor that I think is the point view of understanding about the digital currency .
Most of the people in this world are happy with their routine work and they don't want change that works and they want continue to work like that so here I don't think that they will see digital currency as a better option in Thier life , they will only go with the Fiat currency system .
So a type of understanding will not make them in favour of the cryptocurrency , even if they know very well that how much they can make and what they can achieve in Thier life .
So better for us to show our power that what we can do with the cryptocurrency and make use of cryptourrency as much as possible in our daily life to.give a better place to the cryptocurrency in our life .
