heard of bitcoin as well from 2011, i don't have any idea about it besides being used as an anonymous currency in the deepweb.
if you think bitcoin is kind of expensive right now because people back then bought them cheap, think again after some years later and compare the gap of now and then. don't take my word for it but it will continue to grow.
If you don't have an idea of the applications of Bitcoin that spread beyond the deep web, you should research into the amount of places that have started to accept it as payment. Furthermore, look into the blockchain technology advancements. There have been pushes to implement the technology in numerous areas across tech companies. The more widely accepted it is, the more widely accepted Bitcoin is.
