However, in 2021, there was a backlash against donations in bitcoin because of the environmental emissions it caused.

Mining for proof-of-work cryptocurrencies requires enormous amounts of electricity and consequently comes with a large carbon footprint due to causing greenhouse gas emissions. Proof-of-work blockchains such as bitcoin, Ethereum, Litecoin, and Monero were estimated to have added between 3 million and 15 million tons of carbon dioxide (CO2) to the atmosphere in the period from 1 January 2016 to 30 June 2017. By November 2018, bitcoin was estimated to have an annual energy consumption of 45.8TWh, generating 22.0 to 22.9 million tons of CO2, rivalling nations like Jordan and Sri Lanka. By the end of 2021, bitcoin was estimated to produce 65.4 million tons of CO2, as much as Greece, and consume between 91 and 177 terawatt-hours annually.
On 13 September 2018, Homero Josh Garza was sentenced to 21 months of imprisonment, followed by three years of supervised release. Garza had founded the cryptocurrency startups GAW Miners and ZenMiner in 2014, acknowledged in a plea agreement that the companies were part of a pyramid scheme, and pleaded guilty to wire fraud in 2015. The SEC separately brought a civil enforcement action in the US against Garza, who was eventually ordered to pay a judgment of $9.1 million plus $700,000 in interest. The SEC’s complaint stated that Garza, through his companies, had fraudulently sold “investment contracts representing shares in the profits they claimed would be generated” from mining.
