My advice is incredibly simple, you need to learn how to control your emotions because during a bear market they are your worst enemy, when the price begins to go down it is completely natural to be afraid of what it is to come, especially since we know that volatility in the market of cryptocurrencies is very high, however you need to be able to manage those emotions because if you are not able to do so then you are going to sell for a bad price and lose a lot of money.
