Thx. Finally a third-party diagnosis of my idea..
Yes - I have been thinking something like this, in fact that is why I say in my last post :
By which I mean that if you want to SPEND the coins it has to be done using CASH, you can't spend/send GOLD. This is the reason for switching from one to the other. You want to save you buy gold, you want to spend you sell gold.
Therefore CryptoCash is the Medium of Exchange, and CryptoGold is the Store of wealth. Like 2 sides of the same coin. You can't use CryptoGold as the medium of exchange, since you literally can't sent it to an account. You can only BUY or SELL it on the Chain.
How about if the inflation wasn't done on all the wallets ? you could simply give the new coins to the miners ? I'm not sure how the demurrage would work though in this case.. Maybe only expand.. Seems a technical cheat though.
What I want, is a currency that grows/shrinks in line with economic growth. And i'm trying to find a financial relationship that tells us how much to expand or contract the money supply.. and it must be fully crypto based.
I do think demurrage is a good monetary construct, but my only issue with it is whether the General Public can deal with it Psychologically ? Not even a financial issue.
This is the crux really. As you say 'Each party can gain ONLY by being correct in it's prediction AND in finding a willing counter-party to take the opposite side of the deal.'
This could be done with an on chain exchange, sure. What the 2 sides of the trade are, seems the problem..
I did have another idea. The K Percent Rule. Keep it super simple.
Pick a percent increase, say 5%, and simply use that, forever. Then the CryptoGold would be the 'pressure valve' that you could jump in and out of. When economic growth out performs monetary growth, the price of CryptoGold would go down, and when economic growth under performs monetary growth, the price of CryptoGold would go up. Quite like this one actually.. just means the money doubles every 14 years.. exponential increases are always tricky though..
