if it was a Willy bot then price would have been rising still!
the only reason why price stopped rising back in 2013 was because Mt Gox stopped woking and they scammed and ran away. otherwise it kept pumping it for longer.

we are not in a bubble either. the bubble stopped at $2900 and was corrected when it fell down to $2100 and recovered to a stable price of $2400-2500. this is only because of BIP148 split panic
