If you have a dream to become independent and you work hard for it, you will do it. There are endless possibilities, especially for a growing technology like blockchain. And if you are a programmer you need not to worry. A friend said she know a head hunter who told her that for every programmer there are 8 jobs here in Norway. If you quit your job, you will always find something to do. The best is to make an idea into reality and doing or own projects if you can. I also experience this getting regularly requests on linkedin for jobs. I would recommend to start it as a hobby, and when it starts going good you can quit your job. However there are plenty projects you can work on where they are your client and you are your own boss. Once you quit a job you will start to see all the possible ways to earn money.
