I think that the market would have crashed anyway even without the segwit to be or not to be controversy. The reason being because it has risen too quickly in the last few months and a fast appreciation in price like that brings in a lot of speculative investors and when there aren't enough of these people left to keep buying the price crashes. I wouldn't be surprised if we enter a longer bear market now regardless of what happens with Bitcoin next month. However I don't expect it to last as long as the bear market that started in 2014 because there is now more confidence in cryptocurrencies and people can see that it has already recovered from a very big crash before
