About oooooooo.dev

oooooooo.dev is an independent website publishing free, data-driven crypto calculators: dollar-cost averaging (DCA) backtests, "what if I had invested" simulations, and network fee trackers.

Pages are generated automatically from public market data and refreshed on a schedule. We do not sell crypto, hold user funds or keys, issue tokens, or give personalised advice.

Methodology

• Historical prices: weekly closing prices (USD/USDT) from Binance public market data, plus a daily refresh of the latest price from CoinGecko.
• DCA simulations: a fixed USD amount is invested on the first available weekly close of each period; fees, spreads and taxes are ignored unless stated.
• Network fees: estimated from public RPC endpoints and mempool data; actual fees vary with wallet settings and congestion.
