I personally, learnt to always take profit.
I myself believe in the principle of always take profit. Because I don't like to wait if there is a profit from my investment whether it is less or more. A good opportunity came this week to make some profit. The market was dumped a lot this week. So I invested some USD and then sold when the market pumped again.
I do agree that it was a big drop, but that doesn't mean that we should be focusing on the drop and going all the way to USD because lets not forget that it was printed so much. Yes, the value is growing a lot recently, but that is because of the interest rate going up too, at the end of the day we are talking about 30+ trillion dollars and thats not easy to just hide, and that means dollar is not as valuable, just hiding the drop in the value thats it.
Bitcoin on the other hand is super valuable and will grow beyond ATH again, its only matter of time, when the time comes that will happen and you will want to hold some bitcoins when that time comes, or you will be upset.
