Something weird is going on, but maybe it is just a glitch
Yes, you are reading that right. World Coin Index has Litecoin as the #1 coin on their index.
Live Coin Watch and Cryptocurrency Market Capitalizations (Coin Market Cap) both still have BitCoin at the top.
There was a DDOS on Bitfinex exchange a few hours ago and people were still complaining about orders going through. I don't know if that is the reason for this glitch.
Keep an eye on it.
UPDATE
Adding screenshots for the other two indexes.
Let the positive energy sing!
More Power to the Minnows!!

I'm not sure what this glitch will do, because I don't know how many people watch World Coin Index
you have it based on 24Hr volume instead of total market cap
That explains a lot, but it doesn't explain why the volume of LTC transactions has suddenly spiked. Nor the value of said coinage.
Filtering doesn't change the Number Ranking value.
It was only a matter of time before people moved from gold to silver aka from bitcoin to litecoin.
No doubt. Its a way better platform. Bitcoin is slow and expensive. Litecoin is fast n cheap.
I have a feeling my FOMO of Today will almost look alike a repeat of this article.
