Reading the Bitcoin numbers
The three-year weekly schedule made 157 purchases and accumulated 0.2351 BTC. The average cost of $66,777 sits below today's price of $77,273, so the position is in profit by $2,468.
Along the way the portfolio fell -44.0% from its peak at the worst point. That is the number to sit with before committing to a plan: if a drop that size would make you stop buying, the schedule is too aggressive.
Starting date changes everything
The table above shows the same BTC at different start dates. Returns swing widely because a schedule that begins near a market top spends its first year buying into a decline, while one that starts in a trough compounds from a low base. Use the date pickers to test a start you actually have in mind.
