Can cryptocurrency become universal means of exchange. I mean can it be a global legal tender like the physical money
I dont think that decentralized cryptocurrencies will replace government currency but they probably will eventually be used as an alternative form of payment to credit cards and PayPal. I also think cryptocurrencies will have other functions like store of value or specific functions like internet of things or data storage or various other uses that these altcoins are being created for.
I also expecting cryptocurrencies as means of payment online but not as to replaced the existing local money since it would require a device and energy to operate unlike flat currencies that can be used directly.
yeah right, i also think like that, because it can't possibly replace paper money because the picture of the banknote from each country is a hero of the country, so it's impossible for bitcoin to replace that, i just think bitcoin is used as an alternative just as you say
