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.
It is not difficult or bad to choose for both which everyone is doing and because of that Bitcoin has a value. It is to start business using Bitcoin as a currency. If anyone want to start business and do not want to leave Bitcoin then he have to start a business using these currencies in their dealings.
