“The system equates one tradepoint to one euro, and lets users barter directly or rack up the digital currency...”
Sounds more like a replacement for the Euro. While we preppers like to fantasize about a barter economy, the reality of it is very unlikely to take place. For example, if I have extra toilet paper, but want (or need, whatever) cigarettes - am I going to go door-to-door in my neighborhood trying to find someone that both needs toilet paper and has cigarettes to spare. Sure those people exist, somewhere, and hopefully they’re home when I ring their doorbell. There’s a reason that currencies have been around for thousands of years and will be around for thousands of years into the future.
Bottom line - have cash around, even if you have goods to barter. Better yet, have gold and silver around too. But don’t expect to feed your family very effectively by trying to find people that will barter rice and meat for your extra Size 9.5 shoes...they’re just not that easy to find.
I am so screwed.
