The most "green" story with bitcoin occurred in 2023 when the company Square (now Block) invested $20 million in mining $BTC using renewable energy. In collaboration with solar and wind farms in Texas, they mined 300 BTC (around $12 million at that time), reducing the carbon footprint by 70% compared to traditional mining. By June 2025, these coins would be worth $28.3 million (at $94,500 each). Elon Musk praised the project on X, calling it the "future of crypto." The community noted this as a step towards the sustainable development of BTC. The story inspired others towards eco-friendly solutions, showing that bitcoin can be not only profitable but also "green."
