From my own perspective due to the observations of how the market is going now knowing fully well we're in a bearish season due to the strong market crash just about a while ago which has made the market unstable till date, I think now is the best time to invest, knowing that all coins have lost value and are in massive dip right now, but if investing, your target should be Altcoins and not really Shitcoin (Not a financial advice though) and before going into any trade like I'll ways say, please make sure you do your own Research (DYOR) and always learn to invest what you can afford to lose.
investing in crypto right now in this dip isn't something you'll invest today and take tomorrow, my kind advice should be a long-term investment with the expect of atleast 30-50x minimum.
