There is a huge competition between cryptocurrencies, many believe just dynamic and self fulfilling ideas with different properties and a variety of incentives may survive! Others expect fiat money will leave behind reliance on quantitative competition!
I think cryptocurrencies are not able to defeat fiat currencies without changing nations culture and ethics! what do you think?
because that's what happens fiat will never be replaced by anything even though bitcoin has been adopted all over the world
but it is undeniable that bitcoin as a tool to achieve one's financial freedom in my opinion
