There is no need to convince people to use digital currency. They will eventually adopt. Technology is starting to reach every part of the world and we humans can adapt easily to every innovation that we see.

One's curiosity kicks into those that haven't adopted it, they'll start to know more about it. Information can easily be found through searching and they will learn through many resources that they can find online.

Mainly, it is about a habit and also rules that are used in the country. We know that paper money has been used for a long long time ago, after the barter system. Paper money was Issued first by China around 770 B.C as source here.
And until now, this is still used by most people around the world, moreover like in my country. there are still so many traditional markets and also merchants so that they only accept paper money/coins for payment method. Most of them don't know about digital money, moreover the generation of old people. It is too difficult to introduce digital money to them.
Moreover, digital money itself is still new, existed because of the development of the technology era.

However, I also believe that the era will be still developing and the use of digital money is now spreading so fast. Banks also offer digital systems and also we can find out many e-wallets offering digital payment and transaction methods. And they can be accepted easily.

And I also believe that the era of cryptocurrency is payment is also ongoing, introduced to the worldwide may not be easy enough, but it is on the process. Although in my country itself, crypto is still not legalized as payment or transaction (only legal as commodity asset), I believe that many countries out there will be accepting crypto as one of the currencies.

Let's see how this world will be more friendly to cryptocurrencies

Our situation right now regarding digital currency and how it was 10 years ago is already a good indicator that things are indeed moving in that direction. But it's not just the thing of convicting people to make the switch. This has to come naturally and gradually. For everyday folk stability, security, and investments from the sectors outside the digital realm work as a good selling point. People still look at digital and see issues with fluctuation and security (maybe not security per see, just their perception of security), and until that is taken care of, we can't really expect people going for it. But again, comparing it to 10 years ago, there is some progress.

You don't have to convince them. That's the thing people don't get - if we want these things to happen naturally, we need to let adoption go on its own. All we can really do is just make things much simpler for the average Joe to understand so that learning about BTC isn't a burden. As years go by, today's children are going to accomodate way easier to blockchain tech than we've been able to. So in my opinion, all we truly need is time.

Actually  we've been using it already for a while now. How you would consider those credit/debit cards we do had? Fiat can go digital and we have already seen that one.
Now that we do have another alternative which is on crypto then thats really a good add up but as expected it isnt really that adopted on full global scale due to some issues
like decentralization and lack of knowledge for people worldwide.Adoption isnt still on full scale yet thats why its no surprise that still lots havent able to know on cryptocurrencies existence.
Lets not just push up or force for us to believe on that making some comparison between crypto and with fiat. They do have their own purpose.

Paper money is one of the old fashion which is still though part of our system, but with time the paper money will be the things of the old. Governments are trying their best to create CBDC while decentralized cryptocurrencies like bitcoin are on their way to go mainstream. But what is on ground now is still the digital fiat, fiat are fitting into the new era world also, it was paper money before but now becoming digital money too which can be kept and use electronically. What I just see about the new world is that all these money will fit into it to make the world a better place but those who invest in decentralized currencies will be the ones to still benefit in deflationary currencies like investing in bitcoin.

No need actually to convince them to join in the digital currency. Let them come to find out the benefit of the digital currency and how they could earn. If we wish too that all of them will going to join at once then we could not get the thrill of how bitcoin market evolve. All has the process and I bet bitcoin is already making its way for thw users and to the upcoming bitcoin users in the future. Well, let us hope that there will be another bitcoin ATH in the future like this bull trend.

 IMO
Well my friend you can still buy things with bitcoin using bitcoin debit card there's dozen on the internet neteller payeer crypto.com etoro you name it after get MasterCard you can spend it on anywhere oh and also if paypal development about crypto have progress maybe the store that accept paypal is start accepting bitcoin. Newegg, Vultr, Namecheap and many more is already crypto as payment


Total agree

Paper money is still needed because it is people money that we use everyday in our life to buy our needs and needs. They can adopt the digital currency like bitcoin to make more money or fiat thay they can spend to their daily needs. But the others wants to die the paper money which is not happen , we can both use digital money and paper money now because it is both important.
