As much as I'd like to believe that Litecoin's volume is 7x that of Bitcoin's, I have to be realistic. Here are the top 5 exchanges' volume according to cryptocoincharts.info:
OKCoin LTC/CNY 55.7100 CNY 123,155.3707 BTC
BTC-e LTC/USD 8.90000 USD 4,116.3697 BTC
BTC-e LTC/BTC 0.01433 BTC 3,794.4702 BTC
BTCChina LTC/CNY 56.3600 CNY 2,462.2968 BTC
Bitfinex LTC/USD 9.18800 USD 1,740.1896 BTC
It's really not believable that OKCoin did 123K BTC in volume. That's 30x more than the next exchange. And it's $77 million in trade volume! That's not realistic even with 0 fees.
But even if you remove OKCoin's numbers, Litecoin's volume is still pretty remarkable. Here's coinmarketcap.com's top 5 volume coins:
1 Bitcoin $ 12,296,600
2 Litecoin $ 7,469,600
65 ShieldCoin $ 547,879
7 Dogecoin $ 279,582
58 TorCoin $ 251,851
Given that Bitcoin's marketcap is 30x that of Litecoin's, having 60% of Bitcoin's volume is pretty remarkable. And look at the next largest volume. It's less than 1/10th of Litecoin's volume and it's a coin that's likely being pumped and dumped. When I say Litecoin's volume dwarfs any of the other altcoins, this is what I mean.
