That is very cool, although it is not an unusual thing nowadays. Fortunately I have seen a lot of initiative from Bitcoiners to help out in many situations such as Venezuela and Ukraine. I really do believe many of us here are well intended people.
At the end of the day, we are all just normal people trying to diversify our options and not only be limited to fiat money. Contrary to what the government thinks, bitcoin users do not only use bitcoin for illicit transactions but also use bitcoin for the benefit of other people.
It is why I rather support other initiatives or, my personal favorite, I rather just save up my own Money and do good deeds by myself. This way I can choose some body who I know for sure needs the help I am offering. But that may be just me.
I think you can try and do both instead. You can save your money and do good deed by yourself while also donating to huge charities with other purpose than yours. Habitat for Humanity Intl. is an organization that build homes for those who need it. I find that donating to large scale charities can help more people as they have more reach and more resources and they have the actual time to build the necessary infrastructure.
Right now, I cant just build a house no matter how much money I save up. So I can help in other ways. I can instead do a feeding program. You can do both.
There cant be too much kindness in this world.
