I think this may be a little misleading. If you look at both coins over their entire history, you can see they have similar ups and downs in terms of number of transactions per unit time.
No, I really don't see that, especially after enabling 7-day avg on the bitcoin chart. There is no comparison actually. BTC has a steady uptrend and LTC is all boom and bust with major drops offs. BTC rarely if ever drops 50+% while LTC drops 75% repeatedly, including the current drain spiral.
