Thats kinda hard to predict when the bull market will comes.
Living my first bear market is actually teaching me to take profits in the best bull market without thinking "I'll wait for the bull run ATH".
I will probably begin to sell my fractions of BTC and ETH when they will reach the previous ATH.
Your comment is simple but reveals a great rule to follow: don’t be greedy and set a goal to sell when the price fulfills your expectations. I also have BTC and ETH in my portfolio and plan to sell the fractions whenever the prices reach the previous ATH or even a bit lower. It’ll never be too cautious.
