During the bearish market trend, my strategy is to keep investing, keep HOLDING sure bull run will commenc to bring in the profit, but ensure you research well before investing, consider token with an available product and already listed on coinmarket.
Bearish market is a good time to invest for hidden gem coins. Though it will require you bit of effort but it will be rewarding afterwards. Research and studying the coins and market will guide you which coins have potential to become valuable. And yes, working product is one factor to consider in choosing a good project to invest with.
