In my view, it depends on which side of the bitcoin and crypto world you belong. There are investors and there are enthusiasts. The investors are worried but the enthusiasts are not. The enthusiasts are more concerned about the success of the entire adoption of cryptocurrency as the means of financial transactions. This is being achieved irrespective of the volatile market created by the investors.
I would say both parties are worried about a drop in Bitcoin to different degrees.
Bitcoins value affects the price of altcoins so a drop usually pulls down other currencies with it.
This is a situation that every cryotocurrency inclined individual should be very used to, prior to 2018, volatility has been very prevalent in the market with sharp pumps and dumps.
