The world is big enough to accumulate any Star, I don't think paper money will ever be rejected, it would still be accepted as legal tender in the purchase and settlement of bills because money is money.
But I have these feelings that says in the next few years, paper money won't be as widely used or carried around by people as it is today because the adoption of digital currencies (crypto) is coming in spheres of light every day.
More people are beginning to understand the value behind digital currency, digital marketing and online business are becoming known every day, then to further analyze this, it is true that people will no longer move around with paper money in the next years. As we do it now.
Also, no one likes stress, people like something easier, it is only a matter of time before crypto currency adoption starts to dominate the minds of people who had little idea about digital assets.
The benefits I see towards the more widespread adoption of digital currencies.
convenient, anyone can initiate the transfer at any time, be it at midnight or during the day, and it will arrive at the destination, once the recipient's address is correct.
It is not stressful, it is always in the mind of men to make the world a better place, how can men achieve this in finance? Imagine going to a bank to make a payment, you would have to queue, if you met so many in the bank before you, that's stress, you're going through, meanwhile that same time should have been used for something else.
It Saves time to invest, to save time is one of the best good things in digital assets, I see it as the fundamentals of what digital assets are trying to achieve, time equals to money.
It reduces expenses of unnecessary charges , there is no charge installed in the transaction, apart from the gas fees of the network, why would anyone not take the way? I see digital assets dominance booming in years to come.
