These look good, but for the love of god - proofread! I started reading about NXT vs Bitcoin and in the first sentence - "world wide". Then its "fly by night". Made me chuckle actually, thinking of Batman "some fly by night!" Epic superhero cryptocurrencies fly by night and save people from greedy bankers.

And add sources. Without sources any infogrpaphic is just a PR brochure with hype.
