Cryptocurrencies are becoming more and more common. Will they replace traditional currencies?

Is there a chance that cryptocurrencies will not only enter the world of finance permanently, but even replace traditional cash? For now, no one can imagine it, but several years ago did anyone suspect that we would pay for even the smallest transactions with a card or a mobile phone?

A dozen or so years ago in Poland we heard about attacks on grocery or liquor stores. There was always a few, sometimes even several thousand zlotys in the ticket office, which tempted the robbers. But over time, that began to change. Not only cards were more and more common, but most of all payment terminals. Today we even have a situation where, under the "Digital Poland" program, terminals are distributed for free - it not only affects security, but also greater control. Card payments prevent, inter alia, tax avoidance. This is important for the state and supervisory authorities, but also for entrepreneurs. More and more people simply do not carry cash with them and if they cannot pay by card, they simply go to the competition. In short - everyone benefits from the universality of cashless payment. 

The BLIK service, i.e. contactless payments by mobile phone, is also entering the market. You just need to link your bank account with it and you don't even need a card. In short: cash is slowly becoming a thing of the past. Even those who have avoided them so far are convinced of non-cash payments. The reason is simple: it just pays off. Banks use financial incentives: with 10 card transactions a month there is a free account, for purchases above a certain amount, you receive, for example, 5% cashback, or bonuses from partners: cinema tickets, restaurant tickets, etc.

Cash is gone, time for cryptocurrencies?

Since cash is becoming a thing of the past, can you say it's time for cryptocurrencies? Yes, for many reasons. Investing in Bitcoin (this can be done e.g. via Bitcoin Era) and altcoins is so common that banks even issue payment cards for cryptocurrency wallets. They work in the same way as the payment cards of traditional banks. With the slight difference that during payment, they convert cryptocurrencies into the currency in which the transaction is settled. It's convenient because it doesn't require any involvement from the user. 

Earlier, in some countries, there were establishments that accepted payments, e.g. for burgers in Bitcoins, but it was more of a network promotion than a practical solution. Thanks to the self-counting cards, it is much easier. 

In the case of cryptocurrency cards, the bonuses are even greater, and they are offered by more and more blockchain networks, so it's no wonder that they are becoming more and more common. And from here it is only a step to replace traditional fiat currencies. Since cryptocurrencies are more secure, faster and easier to use, and the state does not lose control over the flow of funds, it is just a matter of choice. Placed on a blockchain, impossible to counterfeit or reprint as a result of a political decision, cryptocurrencies have all the data to replace fiat currencies faster than we think. 

Even 10 years ago, a small group of technology enthusiasts heard about cryptocurrencies, and blockchain technology remains black magic for many to this day. But do we have to understand the principle of operation of a mobile phone or even a microwave oven to use them and enjoy the opportunities they offer us? We do not have to and often do not understand, which does not mean that they are not common devices. Everything points to the fact that cryptocurrencies await the same path.
