What is more efficient? Be a programmer than gives you huge salaries for every project and codes? Or a Bitcoin trader, earner, etc.?
Being a programmer is a way different to being a bitcoin user. Yes, both of these are available to be used with such technologies but they work with different functions. But, this could happen that you can acquire both of it by just being a programmer who chose to be a bitcoin user as well. Since programmers are into computers, then you could use those acquired skills to incorporate into bitcoin.
