How long does it take to become a blockchain developer with no experience if you sit and study 6 hours a day? How hard is it to find a job and what is better to choose rust or solidity?
Takes years to get good. Takes months to be ok. Give it a try, in the end, it's a life skill that will only do you good long run, even if you don't end up as a blockchain developer.
It's all flashy now, and pay is good, but maybe it will be obsolete in the coming years. Why not try machine learning and AI?
