Again, that is a feature, not a bug. Inflationary currency means that you need to invest money, not just sit on it. Deflationary currency means that an investment must provide returns more than what would be gained by just sitting on it.
After all if deflationary currency is worth more tomorrow, one wants to make sure an investment in the future is sustainable.
Notably one is especially interested to invest in a deflationary economy because the gains are multiplicative.
Bitcoin inflation rate per annum: 3.87%
USD Current inflation rate for the United States is 2.7%.
Aprox 4.11% of Bitcoin users (addresses) control 96.53% of all bitcoins in circulation.
What is that called? It's not deflation.
Saving is a perfectly viable choice. If someone wants to save, it is not for you or your cronies to tell them they can't, or that you must shave your cut off their savings each year.
It's a myth that people won't spend. People will save the good money and spend bad money. The bad money is still getting spent, but of course, it's constantly losing its value.
The difference is the perspective on how money should be spent. Savers are low time preference people. They would rather spend their money on the future, on things that last. High time preference proponents on the other hand, only care about the next quarter, will cut corners to maximize their short term profit, and will spend their profit on cars and other depreciating assets to avoid paying the tax on their profits. They also build products which are intended to fail, so that the consumer has to buy the upgrade in a few years.
