True, I can see exponential growth of Bitcoin community in the coming years.
There will be and time to time it will happen in the future.
Well, I don't think bitcoin can help unless if someone will his/her fiat money and exchange it to bitcoin then you'll be able to donate it. In that way you can promote bitcoin and many people will find bitcoin very helpful to them but if you mean that bitcoin itself well bitcoin can't donate to anyone or anything.
