What's new
New pages, data and features on onlytwenty.one - curated in plain language, newest first.
v3.1.0
Price history back to 2010 & real euro rates
Price data now reaches back to the start of trading in 2010 - and every euro value uses real historical ECB reference rates instead of an approximation.
- New pages: Bitcoin return 2010 & 2011
- Euro values day-accurate from real ECB reference rates (no more flat factor)
- Currency can now be switched on every page independently of the language
- Live numbers on the dashboard and stats bar animate on change
- Our own Bitcoin node as the primary network-data source (mempool.space as failover)
v3.0.0
Launch of "The 21 Data Lab"
The site was rebuilt from the ground up from a previous news project into an owned-data Bitcoin statistics site - EUR-native, cookieless, no paywalls, no AI text.
- Calculators: DCA, what-if, converter, fees
- Live network data: dashboard, mempool, Fear & Greed
- Our own statistics: price history, volatility clock, whale tracker, all-time high, halving and more
- Node explorer with our own world map of all reachable Bitcoin nodes
- Everything computed from our own price database - deterministic, no AI
