If you have already invested then you do not need to put your extra money, unless you really feel there is a big opportunity in front of you.
In the bear market, you cannot expect the value will grow, most of us maybe are still expecting that the price may skyrocket anytime because it has happen in the past, but this time, we are facing a big problem as bear prefers to stay.

Now is the time to relax and if you can hold, it's better that way, just don't compromise your extra money if you have enough to hold.
