good post friend puts us to think many things for example 1: it will be that the CRIPTOMONEDA IN A FUTURE WILL REPLACE THE MONEY IN CASH, 2 will be that it will have the same security that has the money in the banks, or we will have the risk of losing it by some haker that is put in the network. I think that nowadays there are few businesses in the world that are paid in cryptocurrency but as this currency and confidence continue to grow I think it will be the best alternative worldwide, as well as less and less people pay in cash and more with debit cards in the future people will pay only with cryptocurrency.
And I can also add that the cryptocurrency has been a solution or help countries where people are drowned by their economy such is the case of Venezuela and India I think are the countries that this year have joined with the largest number of people to the platform of steemit as an economic solution to the crisis that these two countries present as they get cryptocurrency in this case steem or steem dollar and change it to the currency of your country is much higher than a minimum wage being a solution for dress and food..........
