I see the same pattern, pump at least 50% of the previous high, dump, pump to recover and after this 5 hours of peace and then it starts again.
+1
probably with some extra iterations.
i think that first dump ~90 mins ago went "too fast", it had only around half the volume of this one.
Anyway, i am not touching my wallet, don't even have 1 BC left on mintpal so i can't get carried away whatever happens.... Couldn't care less how others battle for a quick buck there.
