For weak systems, hackers may be able to power with this. but is the paper money safe? many corruptors you will make friends
i think between that physical and digital money has its own advantages and disadvantages. but clearly government can not resist development of technology, so that later will also be legalized by government
There is nothing perfect in this world and an invention of human can never be without a flaw. Definitely, digital currencies has its own pros and cons and same stands good for paper money. It is the need of time that decides what someone is going to pick between both of them.Digital currencies are according to the requirement of present and future where speed matters a lot.
Yes, nothing is perfect in this world and something or some people must make a huge sacrifice in other to achieve some greatness but I still don't think the world without physical currency will be fair for the poorest.
