CryptoGotchi is an open-source crypto companion built for the Raspberry Pi Zero 2 W and a Waveshare 1.44" LCD HAT. It turns a tiny low-power computer into a living desktop crypto terminal with its own personality, XP, levels and market mood. CryptoGotchi tracks up to 50 assets, uses CoinGecko market data, stores recent history locally and provides technical analysis across 15-minute, 1-hour and 4-hour timeframes, including trend, support, resistance, range and breakout detection. A web dashboard on port 8080 gives access to market analysis, asset management and companion features from any device on the local network. Wi-Fi, Bluetooth, economy modes and data-saving options make it suitable for continuous operation. The project is designed to be compact, playful, useful and hackable: part market monitor, part virtual companion, and part Raspberry Pi experiment.
