It seems like words, buy when there is blood on the road at this time is not good, because I have done it and the condition has not improved, and prices continue to decline, maybe this will take a long time to recover, better waiting for a better time to return to the stand and at this time it is not possible
It's advice for the long-term investors not for traders or flippers. If price will down again it will be another chance to buy more and cheaper. For good trader any market state can be chance to get profit. But on uptrend it's simpler
