Reading the Bitcoin table

The spread between the best and worst starting year is the whole story of BTC: 2019 turned $1,000 into $20,353, while 2025 turned it into $817. Same coin, same holding discipline, different entry.

Annualised return is the fairer comparison across rows, since a purchase in 2018 has had far longer to compound than one in 2026. Worst drawdown shows the deepest fall each position took from its own peak, which is what a holder actually had to sit through.

If the entry date matters this much

That is the argument for spreading purchases out. The Bitcoin DCA calculator runs the same price history with a fixed weekly or monthly buy instead of a single date.
