Holy mother of god! What happened while I was sleeping? I haven't seen a sudden spike like that since the olden days. What's going on, insider knowledge? Is there going to be some big news soon?
Nothing happend.
Someone pumped LTC with a ponzi to 8$ and traded all LTC for BTC.
Increased demand for BTC short term.
Just basic trading rules.
Makes little sense. Like Elwar said:
The Litecoin market is not big enough to push Bitcoin up $15 by dropping Litecoin by $2.
