I already compute my salary and my income on bitcoin world and it has a big difference between my monthly salary and bitcoin in my salary i get 30,000 Thousand a Month or 625 Dollars a month and thats big amount for me so support my family and my self also and in bitcoin my earnings there are not enough bitcoin is just addition to my monthly salary.
That is a good salary and if you are earning that amount then its better to continue with it and keeping bitcoin as an extra income will increase the level of your monthly income.
Indeed investing small parts into bitcoin will eventually make you money with a way higher interest rate than any bank could ever offer you.
Don't put your whole salary into it though man I wouldn't do that either, you never know what happens ofcourse and you don't want to have to lose all you have saved up!
