Therefore, the interest rate will constantly decrease, and the demand will increase. A bank is a way to eliminate excess emission when it is not needed and give it to the market when it is needed because of high demand in order to prevent such a rise in prices as a bitcoin of several thousand percent a year. It's all simple, you just need to understand.
Bonds are repaid, plus interest. In order to repay interest, entity has to have earnings (or issue and sell more bonds, like US do).
Bonds can be rated AAA, AA, junk etc. This influences the discount they trade at on the bond market.
What earnings Minex has? I can see no earnings prospect other than make pumps occasionally and dump their own coins at the tops. Like all other devs usually do.
I can see your idea is to smoothen supply/demand shocks with taxing miners at various tax rates and redistributing the "tax" to holders.
But as it was pointed out, the devs hold so large a share that shocks in the price will mostly be created by them, not by small punters or "end users" (end users in one of the thousands new coins hardly even exist).
The remedy for Bitcoin volatility is not clever gimmicks like "banks" that are not actually banks, it's simple: less speculative use, less cryptoexchanges-run bots, larger capitalization resulting from that and even less volatility due to larger cap, this is self-sustaining feedback loop.
I see you are quite good at understanding rpb ideas, but you will not understand that this is a completely different project, which has nothing to do with mnx except for a bank.
I think you in vain worry about the shares of developers and their influence on the price in the future. The developer share in rpb is about 3.3% of the total issue of coins, which is not significant at all.
For example, I will give you a coin zec, which does not have any special developments on its use, no innovations, except anonymity .. The developers take 20% of every namnenoho block for themselves !! And their total share will be as much as 10% of the issue.
I hope I persuaded you, at least not much. Thanks for the discussion.
