This donation doesn't accept Bitcoin only, ETH and USDT are acceptable here. So, not only Bitcoin, ETH and USDT are also important in the world. Even other coins are also important although they are not used in this donation program. I agree that cryptocurrencies are very important to use for donation, people can donate with their crypto coins with a low fee in transferring them and they can monitor the number of the coins on the wallet donation easily. It is very different from the donation in fiats, people are difficult to monitor it.
By the way, safe or not depends on the individual. If we are careful enough to do analysis and cross-check before sending crypto coins, I am sure this way is secure or safe enough to do.
Of course they don't only accept bitcoin, so this is a very important thing for all cryptocurrencies. What I want to say here is how much bitcoin has developed in recent years, of course, other altcoins are developing along with bitcoin. We don't even need to talk much about the popularity of bitcoin right now, everyone knows it now
Nearly 7000 transfers have been made so far, more than 150 bitcoins have been donated. More money could have been raised, it would still help Ukraine
