if I can't choose I will do both. open a real business and invest. investing in crypto doesn't take a lot of time. so we can check coin price movements while maintaining our real business. and in my opinion do not rely on crypto investment as the main income because the crypto market is unpredictable. so we need real business or real work as our main source of income.
The real question is, how would you make a business if you don't have a capital? This question is not for royal families or in higher-class people. This question is tend to those who are living in a third world country and middle-class. Getting just a permit is hard enough already, how about getting a loan to start a business?
