Steemit is the next big thing even thought it still in beta for now.. Also about cryptos it is surely the future and it will get more and more developped and enhaced and famous and used ect ... And yes I got almost same reaction then you when informing people about it some of them got really amazed others still don't get it and don't even beleive it's exsitance. Longstory short the big universal hit of cryptos didn't happen yet but once it will happen it will be on the hands of all the citezens of planet earth just like the normal money but now it's time to virtualise it.
