The shortest (simple and straightforward) moving average which hasn't declined even in the deepest bear markets is currently at $58,000. It is the
4-year SMA (simple moving average) - i.e. the average price of the last 4 years.
I think the 4-year SMA is an excellent measure to see if the long term trend is still intact. If this indicator goes down for more than a few days (which can happen in some extreme market conditions), it may indicate that there is a fundamental problem with the long term price trend.
But currently it is going up. Since the start of 2026, it went from approximately 56,300$ to 57,300$ - almost a 2% increase, despite of the declining spot price.
Here's a little chart:

Unfortunately the pic is a little bit small, so I write out the major milestones and year-end values since 2020:
- January 2020: $6600
- January 2021: $7900
- $10,000: March 2021
- January 2022: $18,400
- $20,000: March 2022
- January 2023: $23,300
- January 2024: $29,000
- $30,000: February 2024
- $40,000: November 2024
- January 2025: $42,000
- $50,000: July 2025
- January 2026: $56400
If we could invest in this indicator, we would have
an asset that steadily grows. In theory, it would be possible to realize it with a combination of smart contracts, for example with Discreet Log Contracts.
Would you invest in this indicator? You would lose all the spikes that make Bitcoin so exciting than right now when the price is fighting to hold the low 70k's. But on the plus side: the indicator has only grown until now.
(I am not planning to implement such a contract myself, although I have investigated a bit how it could be done. But if someone would implement that thing, I'd be really interested!)
