Since 1971 the paper currencies have all been losing what they can buy, and the measure is annual consumer prices, with the early years estimated. The Swiss franc did the least bad and it is still down about 66%, the yen is down about 71%, and the US dollar and the Canadian dollar are both down about 87%, while the pound is down about 93% and a long tail of the list is down 99% or more.

You do not need the whole table to feel it, because the grocery bill already did that math, and a paycheck that sits in the paper is working against you. A house or a stock can run ahead of the paper, but then you are an investor just to stand still, and that is not cash in the hand.

Monero beats that chart because the new coins are a fixed drip a vote cannot turn up, and the price can still swing, so this is the supply rule and not a grocery promise. The amounts stay hidden, and the math still shows no coins were made from nothing, and a coin is not stained by where it has been, which the paper chart does not even measure.

That drip is called tail emission, and it has been on since June 2022 at 0.6 Monero about every two minutes, which is 0.3 a minute and about 158,000 coins a year. It was about 1% new coins in the first year, and it keeps falling toward zero, so it is a known trickle next to a printer that stayed open for fifty years. It also pays the miners, which keeps the fee small and the cash movable later, because a reward that goes to zero leaves the miners living on fees alone, and a savings you cannot move is not a win over the paper. People lose coins forever, and the project docs say that once you count those losses the usable pile can still shrink, so the tail is a small known replacement, not a second printer.

If the money is already owed to a bill, it cannot sit in a coin, so spare money is the only part that gets a choice, and the expensive part of moving is getting in and out of the paper, not the send itself.
