As with any productive discussion, it helps to start with a few good questions.
What is digital money?
Is it private?
Can it be counterfeited?
Is it anonymous?
Who makes it?
How does it work?
What happens if the Sun spits out a solar flare the destroys all the digital wallets?
So, let's look at some of the answers.
As long as the computers are secure from hackers, counterfeiting is difficult but not impossible. Fraud and theft would still occur, but we don't know how much.
Digital currency is made by computers working together to pretend to "mine coins".
After a certain period, no more coins will exist, and each coin will continue to go-up in value.
Digital coins can be traded through exchanges, or groups of people who manage computers together to keep track of the money.
If the Sun decides to have a bad-hair day, or if something else happens to destroy all of our computers, we will have to return to another type of currency if one is available.
