that's a natural thing for bitcoin, because the crypto market definitely has an up and down trend. stay positive if bitcoin is at a low price. perhaps the best way is to buy bitcoin and hold it. it would be better than having to watch without taking any action
before buying and storing it, you also have to know when to buy and store it. Do not buy at the price of ATH or the highest price, because it will be very painful. ATH at the end of 2017 alone was able to penetrate again in 2020 and it took approximately 2 years. Buying and saving at the lowest price will give you profit and peace of mind. Never get stuck with FOMO.
