You should not do this even if it is possible to do so. Many people can't accept "free" money due to their immigration status in countries they are residents of. If you send money to them and they receive it they could be in violation of their entry permit rules. So by sending money to everyone in the world you would create problems for a huge population of immigrant workers.
