Cryptocurrency is fast becoming mainstay in the world right now. Frankly, I am not quite sure of all the technicalities involved with it. All I do know, is the fact that it does work. Digital pieces of code having value that can be exchanged for real money. Something the smarts a year ago would've scoffed at for being a potentially ridiculous idea. It is now something that has come to stay.
Personally, I have know about cryptocurrency for a few years now but only just got active in its usage 2 years back with my registration on binance, the world's foremost cryptocurrency exchange, kick-starting my journey in the crypto space.
I really do not think I have enough data to make a very informed decision about my preference of either cryptocurrency or physical money over the other. However, I think I can confidently come to the conclusion that each of them have their place in the world and one does not really have to disappear for the other to thrive. Each of them has its pros and cons and they sort of balance each other out.
