I still fail to understand How database points
We use some sort of "cryptos" on our daily lives. Each time we use the Phone, Card or even auto withdrawal we use electronic forms of payment. The twist is, that a Bank holds those numbers on their database and they use those numbers to do what they please. As far paper, is just a physical representation of those numbers. So what gives its value? People is what give the value to currencies. On this case, the Bank is out of the equation, the owner of the currency hold the Private Keys. You can lose the hardrive, or your phone, if you have the "Seeds" you can retrieve the numbers. They are never destroyed, what you loose is the password that proves the ownership and nobodyelse can take posesion unless it has the Seed or the Password.
Also, we use Dollars because is forced upon us by law, hence the name Fiat Currency. In El Salvador, became Fiat because is legal to use, still, no official currency, but is legal to use.
I say, keep your eyes open and understand how they work, does not hurt to learn. We are on the edge of a technology that is going to hit meanstream. Is going to be a period of adjustment, people are scary animals, they fear the unknown.
