This is just regular baloon popping situation. Nothing bad will happen. Market will recover in couple of months sadly. It won't be that quick. But as I said no altcoins or bitcoins are dead. Ethereum is still alive too.
You are aware that the bear market that followed the 2013 run-up (partly fueled by MtGox) lasted much longer than a couple months?
I wouldn´t be so confident that we are going to experience a falling BTC price only for a few months. Depending on
the outcome of the November fork anything is possible, including a huge drop. Some people even expect a huge
Bitcoin Cash pump near the fork in order to take advantage of the volatile market situation.
Anything is possible in the next few months
