Given a situation where digital currency replaced paper outright, history tells us that its just a matter of time before government becomes so corrupt that they destroy the digital currency. It would likely happen within one generation. Maybe 30-50 years. It takes time for people to stupidly trust such a system. We know this because there are many examples of societies going through it.
After that, gold and silver would make a roaring comeback.
To help you understand why this keeps happening, let's look at something similar that we all should now understand: housing bubbles.
Housing bubbles / real estate bubbles have happened MANY, MANY times throughout human history. Yet they KEEP happening. We just had one in the United States last decade. As the bubble inflated, we heard from MANY confident, smart people that it couldn't possibly happen. People were swayed. They ignored history and allowed it to occur. And then it burst, and many people were hurt.
It will be the same with currencies. Despite the overwhelming evidence that fiat currency is a HORRIBLE idea, despite the numerous currency disasters throughout history, people refuse to learn. I bet what will happen is the exact same thing with the housing bubble. MANY confident, smart people will tell us that a currency collapse cannot possibly happen, that a digital currency is perfectly safe and government won't abuse it. And people will be swayed. They will ignore history. It will be tried. And another currency will be destroyed, and many innocent people will be ruined.
And then we will go back to gold and silver currency. Always happens.

Gold survives economic instability. I agree that digital currency is very unlikely to. Corrupt government will destroy its value to try to "stimulate the economy", or rather stay in office.
