As always, the devil is in paying precious attention to detail
Do cars appreciate over time? I'd rather say no unless you have to wait like 50 years till some exclusive models obtain real value. This is definitely not what car manufacturers want. But is it the same with miners? Again, I should say no as bitcoins do tend to appreciate over time and in less than 50 years, so it does actually make sense to keep at least some of the reward and not sell it in its entirety. Long story short, your analogy is heavily flawed, up to a point where it stops being an analogy at all
It costs money to make a bitcoin. If the miners don't sell how with they recoup their costs? Also bitcoin does not always appreciate. Ask the people that bought at 19k or 13k how well bitcoin appreciates.
My system alerts people when the price is low compared to the creation cost, and when it is high compared to the creation cost. I let people know when the whales are buying, selling, or holding based on logic.
You are promoting an idea that miners have no need for money, and that they will hold their bitcoin simply to see massive price increases. You are even assuming that miners want to maintain sky high prices even when faced with low liquidity and extreme volatility.
Perhaps you should check out my site, and actually read about how bitcoin works:
