Bitcoin price 25 percent below its level a year ago: what you can do now

Anyone who bought Bitcoin on 14 October 2025 is looking at a price today that sits roughly a quarter below their own entry. A year ago one Bitcoin cost $115,226 or 99,310 euros; by Wednesday midday it is $82,709 and 74,239 euros. That is 28.2 percent less in dollars and 25.2 percent less in euros. For exactly this vintage the one-year speculative period under German tax law expires today, and what changes with it is not the price but the calculation behind it. The figures come from CoinGecko's price series for each calendar day.
