It did 10x within a very short period of time. I agree on some part of your comment. Yes, LTC was stagnant because of no new development. It was just sitting ideal because it was almost similar to Bitcoin with minor changes to the core blockchain code. But as Charlie Lee was active again onto it with real good initiative it rose within no time.
That is what he is comparing. Yes, it is a kind of speculation but based on a real case study which happened with LTC since it activated Segwit. I have started liking LTC as well due to its recent initiatives. It's because of LTC's success, BTC went for SEGWIT.
