I am not into offline business yet. If I have a lot of money I will surely engaged in offline business. But as for now I am into cryptocurrency trading and investment.there are two ways to make money.
the first one is to make them online (just from your home) and you earn withdraw that money to your Paypal, Payeer, Visa Card...
the second one is to work outside like in a restaurant, or in a shop and you will get them cash to your hands.
Which way do you like and why!
