The data shows a compound annual growth rate of 107.40% which is way more than any fix deposit income or stocks market. And this 107% is purely Bitcoin, no altcoins or shitcoins.
Basically, you get profit on every year more than 50% except bear years like: 2014, 2018, 2022 and most probably 2026 if we follow the Bitcoin cycle.
These years have been the best time to invest in Bitcoin.
