Ah yes, accusing one of using an LLM, a sure sign of winning the argument 🤣
- Money invested earns deflation + interest.
That's incorrect, money LOANED earns deflation + interest, not money invested. Money invested loses out on the deflation.
You have 1BTC. You exchange the 1BTC for 1 unit of an investment. As BTC deflates, it's buying power increases. When you go to sell your investment, you find that 1BTC still buys 1 unit of the investment, even though your investment grew in value during the same period of time. You could have done nothing to get the same result, without risking the volatile investment losing value instead of gaining. The higher the return needed to outpace deflation, the riskier the investment needs to be. Deflation worked against the investment, not with it.
Inflationary currency motivates investment and consumption. When your money is going to lose some value anyway, you might as well take a risk and invest it for a potential reward. You might as well make that large purchase today, because your money will buy a little less tomorrow. This is healthy for the economy.
You are correct that deflation adds on top of interest, which makes loans more expensive. This stifles an economy by decreasing demand/consumption and the flow of money through the economy. When loans are more expensive to pay back, people are discouraged from taking a business loan and starting a new business or taking out a loan and investing it or using it to make a large purchase.

I think we've reached your limits in this topic.
Lol I'm literally giving you a free education. You should be paying me for this. It's something that you're still responding after your argument has been torn to shreds with my every reply, without fail. The name calling and LLM accusations creep in as you start to realize you're wrong and desperately cling to denial. The cracks are already showing lol. Getting tired of trying to spin inconsistencies? Like I said, it's effortless to just be correct.
