Donations of Bitcoin (BTC) to the Ukrainian army have skyrocketed since Moscow started a large-scale operation against Ukraine yesterday. Currently, approximately $400,000 in BTC has been contributed to Come Back Alive, a Ukrainian non-governmental organisation that supports the armed troops. The new batch of crypto donations builds on a previous trend in which hundreds of thousands of dollars have poured into Ukrainian NGOs and volunteer groups attempting to stave off a Russian invasion, with the contributions only increasing now that the country is officially under attack. Many activists have used BTC for a wide range of purposes, including providing military weapons, drones, and medical supplies to the Ukrainian army, in addition to supporting the creation of a face recognition tool meant to ascertain whether someone is a Russian spy or mercenary. Another organisation, the Ukrainian Cyber Alliance, has received about $100,000 in BTC, LTC, ETH, and a variety of stablecoins in the last year. Since 2016, Alliance activists have often carried out different cyberattacks against potential Russian targets. Pro-Russian separatists, on the other hand, have been soliciting funds in BTC from the beginning of the conflict.
