... but there is an opportunity to lose money if the investor does not have the right investment strategy.
It's not an opportunity, it's what we called the risk of losing money, you only say it's an opportunity if you benefit on it, like if you accumulate cheap coins in the market during the bear period.
The bear market taught us to not fall in love with some particular project. You have to buy it and sell high by tech analysis. It doesn't make sense to keep all the tokens that are tanking. IF you see that the price is approaching to buy price, sell that gem.
