What would happen if you had a currency like bitcoin, where each coin would be produced slowly as now with the bitcoi0n system, but would only last a year, would a system like that enable 'Brakteaten' advantages of driving wealth distribution?
*Brakteaten as in people not hoarding money that will eventually lose value, so wanting it to work for them, thus driving the economy.
Expiring currency does not prevent hoarding. In fact, it hurts the people that work for a wage more and benefits speculators.
Thinking that an expiring currency will avoid hoarding is extremely shortsighted (another discussion would be if hoarding needs to be avoided). The argument is similar to people saying that producing inflation avoids hoarding. Both are utterly ridiculous and for a very simple reason: People dont save all their wealth in money
For example, nowadays a lot of people have their savings for retiring in the stock market. Or most rich people have their fortunes in the stock market as well, in commodities, etc... So in reality, devaluating the currency benefits them because their actives go up in price.
If people know that the money is going to lose value, they spend it and hoard something else that they think is going to keep its value.
And it hurts the people that work for a wage because wages are the last thing that gets actualized. So consumer prices go up, and then, some time later, wages actualize. During the time where your wage is not actualized you have lost purchasing power. This purchasing power that is being stolen, goes to the people that has active that get apreciated by inflation, basically the rich.
So it not only does not prevent hoarding, but it benefits the concentration of wealth, because its a lot easier to defend from debasing money for a rich guy than for someone that earns a wage.
PS: Then you have the problems of distortion in the price signals, leading to malinvestments and less economic growth for everyone.
