Of course, we have plenty of unsung heroes on this forum that I've probably never interacted with in a post. If you ask me who is the true selfless hero then I believe he is the satoshi who created bitcoin for us.

It is clear that the 3 users you are reviewing are forum members who have contributed well to the forum through their knowledge and activities but for me the real unsung hero is satoshi.

There is a list of Most Recognized Profiles that might also be good for you to know, they are also unsung heroes with different capacities and contributions to the forum and also bitcoin in my opinion. Check the list if you want to know who they are.
