With that said, I'd recommend you to lookup some history of monetary systems, and see what systems survived for how long, and how they came to collapse. Just because bitcoins are digital, a product of technology, doesn't make them any different from tally sticks. It's just a way to exchange stuff without having to barter. Maybe bitcoins are much harder to counterfeit then tally sticks, but then again, it is probably also much easier to sabotage the systems required to trade them. In the end, the currency that sticks around the longest when all the other systems fail, will be the most reliable one to preserve wealth. It's a self-reinforcing process even.
Now go try and see how many bushels of wheat you can get your hands on with just exchanging tally sticks. Then try to buy some using gold.
No farmers near me take payment in anything except United States Dollars.
Compared to tally sticks, say, or bushels of wheat, or time-banked labor hours.
