My general take on investing in bear or bull markets within the whole crypto space is, that during a bull market you can achieve the highest potential profit when you invest into new and upcoming projects that have a strong team, a real use case, a roadmap that makes sense and of course also fair tokenomics. Of course even if a new projects is fulfilling all of those requirements then there is still a chance that it will fail and that the money you invested is lost, but that is just the nature of the game in the crypto space.
During a bear market though we have the chance to invest into projects that are already big and established for a discounted price. For my personal taste those price ranges have not been reached yet but if we are in for another few months of bear market i might invest into projects like ETH or BNB.
