do you mean to keep the value low such that people dont need to use "mBTC/uBTC/satoshis/etc"? Most bitcoin software allows you to send payment in mBTC or $USD (converted to BTC value). having decimals is not a bad thing, and if that is a problem for some people even when thier wallet software does the 'mBTC/satoshi' conversion its an issue of ignorance.
You cant use a wallet every time you want to think about the price of something. "Is 0.00023 Foocoins too much for a cup of coffee?" "Is 0.03 milliFoocoins more or less than 3200 Footoshis?"
The smallest unit of the currency should be worth maybe 1/10 of the smallest thing that is worth buying separately. Since it takes at least one minute to make an independent purchase, including the decision to purchase, there is no point having means of payments with a much smaller granularity than the value of a minute of one's time. (That must be why true micropayments have still to find their use, in spite of 30 years of attempts to make them work.)
again, you talk about making bitcoin unappealing so that it is not desirable as a store of value, why?
Not bitcoin; any crypto
currency. I explained why: because a currency that attracts hoarders and speculators is a terrible currency.
you already pay fees like [ the proposed 2% negative interest ] via transaction fees and via the network currently inflating at ~12% (dropping to 6% next year). The concept of 'inactivity fees' is sheer insanity
It is insanity only if you start from the axiom that a cryptocurrency's goal is to rise in price so as to make investors rich. If you start from the assumption that the goal is to serve as a currency, then insanity is what happened to bitcoin.
Bitcoin's transaction fees are too small to destroy the illusion of fabulous gains, and the 12% inflation of the currency base does not directly act on hoarders' holdings, because it is not paid by them but by the new investors. So much so that the price (and therefore the hoarders' paper fortunes) grew by 1000% per year while that inflation was even higher than now.
A cryptocurrency with demurrage tax would fall directly on holders, and therefore hopefully discourage hoarding.
