People always say that Bitcoin is the digital money that will take over soon as the world is digitalized,but they have not understand something, It may not be easy as we think due to some delays in confirmation of transactions,It will be a good development to the whole world, but how do we perfect this and make it handled and easy as a physical money? Bitcoin has actually come to stay an let make it perfect and make it easy for everyone to use, through the digital. Yes I agree that Bitcoin is future currency, but let it be easy to use ?
Well, Bitcoin is developing at its own pace no? At least, well, stuff like lightning networks makes the problems you've said be easily resolved. In addition to that, every medium out there has some pros and cons, there isn't any "perfect" medium out there, just the best fit for what you want. There's probably no need even to confirm the advantages of fiat since there are also the advantages of Bitcoin against it. Bitcoin doesn't need the attributes of fiat to make it a good medium/currency, it can stand on its own with its own characteristics.
