@enjoywithtroy - my thoughts exactly.. although I would have say that there won't be just "one" to replace them, but probably a handful of different cryptos with slightly different purposes (Ie, Ethereum isn't a Bitcoin competitor because they are intended for two completely different purposes). I definitely believe that many will fade away though since we are in a crypto bubble like the dot.com bubble of the late 90's.
Also, "is fast making Facebook and youTube obsolete" is a bit extreme...I'd say that hopefully they will grow obsolete some day, but the staggering amount of FB users and YT daily views proves their undisputed dominance, at least for now. I agree that things will change though - for instance @surfermarly just posted about a decentralized video platform...would love to see that knock out Youtube!

Anyway @ejemai - I'm really glad you posted this, because I had been noticing a great deal of Nigerian users here and was curious to learn more about that. Upvoted, resteemed and followed!
thank you @jobsande, the steemit wave is just now taking a swipe around the Nigerian nation and we are hoping to be part of the game changing blockchain website that encourages productivity
Best of luck to you! :)
