Who has heard of it,...what is it??

A co worker mentioned it the other night, mentioning it went from .01 cents to over $1000, and I checked it out to find apparently its around $3868 now,

I am NOT looking at putting money into as I dont understand it, and dont believe it to be a "true" investment but he seemed pretty sold on it,..just didnt have enough information to fire back with, so to speak
