Title: Is DCA into Bitcoin still worth it in 2026?

I was looking at what would have happened if you invested €100/month into BTC, starting in different years and holding until October 2026.
Here are the approximate results:

I calculated what investing €100/month into BTC from different starting years would be worth today (October 2026).
Here are the approximate results:
2011: €19,000 invested → €78.9M
2012: €17,800 invested → €17.9M
2013: €16,600 invested → €2.31M
2014: €15,400 invested → €879K
2015: €14,200 invested → €634K
2016: €13,000 invested → €273K
2017: €11,800 invested → €97K
2018: €10,600 invested → €53K
2019: €9,400 invested → €38K
2020: €8,200 invested → €22K
2021: €7,000 invested → €13K
2022: €5,800 invested → €11K
2023: €4,600 invested → €6.9K
2024: €3,400 invested → €3.6K
2025: €2,200 invested → €2.2K
Approximate simulation using BTC at ~€72,700. Excludes fees and taxes.
Obviously, early investors benefited massively. But with BTC now being a much more mature asset, can we realistically expect strong returns going forward?

I keep reading about people that got in early and made a killing, and I’m genuinely happy for them. But let’s look at it from current the viewpoint of current day investor, that are just starting out… does dca still make sense?
