People says that bitcoin should be hold for lengthy time of at least 4 to 5 years of duration but I think that I you have maximum profit during bear season in less time then you should sell it because market will not always gives you maximum return.
This is true, when we are holding for long-term one. I don't think we can actually know when is the best price to stop and sell it. Just like you said, it would be better if you need the money and enough with the profit then you can pretty much buy it again in another time. Most people said that you need to sell "high" but they don't know what is the threshold of that "high" is, so just keep ind mind on that.
The desire of getting more and more will make you looser because there is not a single person who is thankful for the money he owned but instead everyone wants to earn more than this.
Correct, we will never be enough with the money.
