Just came across something interesting about market cycles that's been floating around crypto communities lately. There's this old theory from Samuel Benner, a 19th-century economist who back in 1875 was obsessed with figuring out when to make money in financial markets. He basically mapped out a repeating pattern of boom, recession, and panic periods. Whether you believe in it or not, the framework is actually pretty useful for thinking about periods when to make money.

So here's how Benner broke it down. He identified three distinct phases that tend to repeat roughly every 18-20 years. The panic years are when everything hits the fan - financial crises, market collapses, widespread fear. Think 1927, 1945, 1965, 1981, 1999, 2019, with the pattern suggesting 2035 and 2053 coming up. During these periods, the advice is straightforward: don't panic sell. Just sit tight and wait it out.

Then you've got the boom years where prices are surging and markets are recovering strong. These are your golden opportunities to take profits and sell assets at peak prices. Benner's list includes years like 1928, 1943, 1960, 1973, 1989, 2000, 2007, 2016, 2020, and interestingly, we're supposedly in one right now in 2026. After that, we'd see 2034, 2043, and 2054. This is when you're supposed to be aggressive about selling.

The third category is the recession and decline years - the hard times when prices bottom out and the economy stalls. These are actually the best periods when to make money if you've got dry powder. Years like 1924, 1931, 1942, 1951, 1958, 1969, 1978, 1985, 1996, 2005, 2012, and notably 2023. The strategy here is simple: accumulate when everything's cheap, then hold until the boom cycle swings back around.

The basic playbook is buy low during recessions, hold through the uncertainty, and sell high during boom years. Avoid getting liquidated in panic periods - just weather the storm. That's the core wisdom.

Now, important caveat: this isn't gospel. Benner's cycle is based on historical patterns and statistical observation, not some immutable law of physics. Real markets get shaped by politics, wars, technological disruption, policy changes, and a thousand other variables. So while this framework offers interesting perspective on long-term market rhythms, don't treat it as a crystal ball. Use it as one tool among many to understand market structure, not as your sole trading strategy.
