Well if any of my relative or friend's ask me this question, i will shout at them that "Come on we are still in bear market, there's still blood on the street" I will wholeheartedly tell them to invest but first i will tell them that invest what only you can afford to lose.
The market is consistently low and no bull run is coming. I think now is the right time to invest while the price is low. So later on we can get big profit for long term holding strategy.
