Thats your choice, but most of the things you will do these days you will need to make use of cash most of the times. Take for example you got to a local market to buy some stuffs you need, are you going to pay them with Bitcoin or PayPal? Its still that cash that you will need to make payment and thats just 1% out of things that you might across everyday that might require you to make use of cash. Though in some situations you will need just your own credit or debit card, or even an mobile payment app like that of PayPal and the rest of them.
we are always need cash for daily transaction because my country still not allowed using bitcoin as payment transaction, my country still illegal using bitcoin as transaction but legal bitcoin as investment or trade,
Is Bitcoin the only online payment system there is? Why not make use of other way if you need to make use of online payment? And btw there are many other ways that people can make payment, Bitcoin is even the least on the list, cause there are POS and they are almost every stores you get in these days. Then there are mobile apps and the rest of them that you can use to make payments. In my country theres no law that states whether Bitcoin is legal or illegal, so I make use of Bitcoin, but I dont see anyone here making use of it. Its mainly cash that I use. Only make use of Bitcoin for the part time jobs I do.
