Things have changed due to the development of information technology,
last time, to  buy something you have to go to the store, grocery, or supermarket to buy but nowaday, you are only stay indoors and with a mouse click, the goods will come to  your hand.
And the demand for money is different, so the introduction of virtual currency is necessary and Bitcoin is the payment system needed in today's society,
However, bitcoin is still in the basic phase of development period So many people are skeptical about it
I hope the market to adopt cryptocurrencies in the coming years and we should really think about that aspect and work in that direction. Things are still in the black area and it needs time to have the habit of using it as a payment system.It's very necessary!
