After the dip from 100k to 40k people will ask the same question.
That will be a brutal dip. Imagine someone buying 1BTC with his life savings for $100,000 and it drops 60% in a matter of months.
Technically it's the same as when people buy Bitcoin right now with $100,000 and it drops 60% in value, but psychologically a 60% drop meaning 1BTC loses $60,000 is different from 1BTC losing $6000 with a 60% drop at current levels.
On the other hand, if institutions gain an upper hand in this market, we may not even see corrections of that magnitude anymore. It's very likely that we'll see exchanges enforce stock market security measures.
One way or another, the market will change, and if it becomes more stable due to these changes, it's a great step forward to make Bitcoin even more usable as a currency. Stability is key.
