If charity accepts bitcoin then the bitcoin will be more popular. Charity organizations will have more help from the pre-digital investors or bitcoin owners.
You are right it will be good because if a person will have no money to share with charity they will be able to share their bitcoin for now it is good for popularity of bitcoin because it will make it high in demand as well, it needs our support and our investment so lets invest our money as it can make our future bright, for me it will be great news if I will hear about it,
