If someone uses ripple in their presentation like this, I completely turned off and lose my attention.
oh come on, it is obvious he didn't use Ripple in there, because it's world's best cryptocurrency, but simply because he was listing top 4 coins by market cap. and also the thread is called "A beginner's guide to
cryptocurrencies" and not blockchain (in case you want to argue XRP is not decentralized). So cut him a slack and enjoy that infographic.
You've got to admit that it is pretty good.
