Why this period and asset
December 2017 was when Bitcoin peaked in its first major bubble. Right afterward came the so-called 'crypto winter,' with prices falling by a very large margin, followed by several sharp swings. Investing a lump sum at this point means passing through an extremely large drawdown first.
Interpreting the result
This shows the path of entering at the worst time in an asset with extreme volatility. The maximum drawdown was very deep, and the stretch underwater and recovery period before regaining principal were long. Because the swings in between were far larger than for an index asset, stretches that were hard to endure emotionally recurred. Whatever the outcome, the key is whether you could actually withstand such a large drawdown and long recovery, and this case should not be generalized.
Caveats & limits
This result is a hindsight simulation of one specific peak and does not guarantee recovery. Crypto assets are extremely volatile and carry the risk of becoming worthless. It ignores taxes, fees, and currency effects. As a dollar-denominated asset, the outcome in won terms shifts with the exchange rate. The past does not guarantee the future.

Frequently asked questions
Does buying at a peak always mean failure?
Buying at a peak sharply raises the odds of a large drawdown and a long stretch underwater. Especially for extremely volatile assets, recovery is not guaranteed and this case cannot be generalized.
Since it recovered in the end, can't you just hold on?
The stretch underwater and recovery period were very long and the drawdown extreme. Given the asset's nature, recovery is not guaranteed, so generalizing 'just hold and it recovers' is especially dangerous.
Is a lump sum or monthly investing better?
During an ongoing plunge, monthly investing can lower your average cost, but if the asset itself does not recover, both approaches carry loss risk. Neither is always superior.
