Most of these transactions took a few minutes and around $1 in fees. Bitcoin lightning is pennies in fees, but the account shown is on main chain. There are over 19,000 individual donations.

If you know somebody who wants to contribute to Ukraine but doesn't want to deal with the hassle, cost, or availability of international bank wires, this is a great way.
It will go directly to the Govt of Ukraine instead of being filtered through a NGO or other party.
Unlike aid from governments/NGOs this money comes with no restrictions on how Ukraine can spend it.
Most major cities have several Bitcoin ATMs and in many countries you can buy Bitcoin online easily. This means you can have a bake sale or other fundraiser, turn that money into Bitcoin, and send it to Ukraine directly.
