It's good to invest in bitcoin but let us remember that it's a virtual and any money and profit we make in bitcoin should be directed to establish another business that will be seen physically and be managed physically.
Running your own business sounds like a great deal, being your own boss and keep all the money you earn for yourself is the goal of many people. But we should not think that a business owner is always going to succeed and become rich. A lot of businesses fail and the working hours of business owners is usually much higher. I don't think there is anything wrong in being an employee and use your monthly income to build an investment portfolio on the side. For such people like me taking out all the profits out of Bitcoin might not be the best idea, because I don't really have so many alternatives to invest in.
At the end it all depends on your priorities and having a good work-life balance. If as employee you can make, let's say, 7, working your 8 hours per day, 5 days per weeks, would you want to change it for you boss' salary, let's say 10, but then you need to work 10+ hours per day, 6 days a week? I'm not sure I would accept, because it's better keeping your employee job, money is important but if you are the boss that also means more responsibility which is equal to more dedication, more time, and more stress.
