A. There will always be a market crash, as the market does not always go up like a straight line, it is more like a U or V curve. As an investor, you should do three things:
1. Diversify
So some of your money doesnt' fall in value when the market declines.
2. Rebalance
So you can buy while prices are down.
3. Keep a long term focus
So you are able to participate the eventually recovery.
