I would say NEAR protocol is the best option. NEAR has .01 usd transactions and their account system makes it the easiest crypto to use. You can have your own name on NEAR protocol "Sammy.near" and you don't have to install or learn how to use metamask browser extension (track seed words, configure gas fees, configure rpc, add custom tokens etc.). Plus NEAR makes DeFi easy with Ref Finance. You don't see multiple approvals like on Metamask, it's as easy as checking your email.
