I usually do some charity, especially when I make money by investing in bitcoin. I think everybody should be grateful. When you get happiness or satisfaction from the society, you should give back to this society and help those in need. But donating bitcoin is not the best way, I will choose another way.
The first time I came into contact with charity that I made money when investing in bitcoin, I was so grateful that I wanted to help some poor people. So I financed a child to college, she is now in her junior year, and is about to graduate. She always wrote and thanked me. I think it's true that we help others in a right way.
