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?
Many blockchains will be adopted, each geared towards a different purpose. For example:
xrp- remittance/derivatives
xlm- cbdc
HBAR- logistics/carbon credits
ICYp- transform web2 into web3/social media/metaverse
