Stellar Lumens is an amazing cryptocurrency. With near-zero fees and almost instant confirmation, it is great for sending funds to anyone, anywhere in the world.

Lumenthropy is a project that supports various non profit organizations by donating Stellar Lumens (XLM). They have joined hands with folks at StellarBattle to help identify non-profits that we would like to see officially accept XLM as a donation option.
