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?
Been a developer in blockchain isn't about the time you spent, it's about how you were productive during that time, that's the only way you can gain experience. You have to be ready to learn, be ready to learn from your mistakes, be ready to adapt to different brochain exposure but most often, you need to know Javascript even when you are sleeping to become an expert, sometimes you have to be in a project for long to understand everything fully.
To be a developer, you have to relate your knowledge to other people, you have to solve some problems for people who have difficulty in some special codes. If you look at this forum for instance, there is a particular board where technical discussion are been talk and most of the time, it's tye developers that helps reply this questions, you will never see an average person talk about script and some special code about Bitcoin, most of the time it's the developers and coders.
