You can buy more, and once the price goes up you will see a value greater than $5 but just like last time, it will go down again. You can't be like this forever but you need to take an action. Why not sell your coins once the price go up? So that your profits won't be dragged down anymore by the time the price go down but you can buy again during that time. You can repeat these two processes until you reach your desired profit.
That is the best way to generate a profit during the bear times. The term for that by the way is trading or it can also be called short term investing but if you are not bothered about the ups and downs, you can also do long term investing.
The chances of making a profit in a bear market are slim, don't expect to make a profit in a short period of time. Even if it has fallen in price, it is not necessarily the bottom, and it may even continue to fall without guarantee of recovery. There will still be certain risks in investment.
Yes, this is absolutely true, I agree with you. It is very dangerous to trade in the short term in the bear market. Especially if you make ambition, you can lose all your assets. To my way of thinking the most important thing to do is to invest in the coins you trust and wait for a long time. In this way, you will not be harmed. As a result, you will have a lot of money left in your safe.
