I’m a fairly new to blockchain development. I’ve been spending sometime learning Solidity to create smart contracts on ERC-20 & BSC test nets. However, I would like to learn more than writing simple smart contracts for tokens that have little utility. I’ve seen blockchains and coins written in numerous languages, but I don’t know which one(s) to specialize in. Google doesn’t have any specific answers. Which languages would you recommend and why?
Thank you for your time.
