It's due to me I tell ya! It must be, 'cause I was arbitraging the living headlights (thanks Fisher Stevens) out of the LTC/BTC cross during the two recent LTC bubble-ups, profiting somewhat in the process. Others had similar ideas; I even watched a guy on YouTube discussing this exact thing for 20+ minutes.
OTOH I generally don't speculate on the BTC/fiat crosses, which does mean I missed out on an opportunity to sell before the recent crash and buy back in lower, but hindsight is the B word, speculating being so easy when you can see the graph to the right as well as to the left.
I wish i could see further right.
