Yes you are right, having a job is just getting some assurance that you are going to have something for your daily needs and you are going to work for it. That is why you need more source of income such as bitcoin if you want to have good earnings and get rich. You don't have to sacrifice anything what you need is proper time management.
If a person can be more productive in bitcoin if he focuses his attention to it, why not? Bitcoin offers a good opportunity to make a lot of money, even more than what an ordinary employee can earn. If a person can focus on that and make it work, then maybe it is worth it to leave a day job and just focus on bitcoin.
[/quote] Are you sure that bitcoin can give you so much to the stable income that can give up other sources of income? There is no doubt in the courses, ie on the difference in price can make good money, but I do not think that this method may be permanent.
