I'm very disappointed! They use to be better than that, they totally misunderstood
BTC.
They consist only of data. And data can be copied without a great deal of effort. There is therefore a risk of the same "digital coin" being spent more than once.
Their conclusion is hardly better:
In the end, the question remains: Who do you trust more, your own central bank or an anonymous online network?
Maybe in Switzerland, people can trust their central bank, but that's not the case in the US or in the EU.
