When we are at Extreme Greed you need to be taking some profit off the table. Most people in crypto fail to keep the money they've made. They either sell too late or they selfishly watch all profits fall back to zero.
I've seen this happening each cycle.
We all need to understand that 1st priority in crypto is surviving. Profits are in 2nd place. Yes that sounds counterintuitive, but it's really simple. The real skill is not in making money. The real skill is in keeping it.
I hope you found this useful. Keep up the flow, and may the force be with you.
I agree with you because that advice is very good for every trader. I was always trying to make as much profit as possible and that's not the right thing to do but to my mind, it's also not good to 100% enter into the game and then 100% leave the game or you'll regret it.
This is my strategy: I invest 100% into coin when I think that price is very low, then try to sell it when I think it's the right time or I wait for a long time. For example, I bought bitcoins in 2022 and didn't sell them till recent days. It's difficult to buy and sell frequently, when I tried that, I instead of making more profit, I missed the profit. If you can't figure out good times frequently, then long-term is the best advice and I think for good gains, everyone has to frequently visit crypto news websites and be in touch with the situation all the time because if there is news that triggers panic, you have to be one of the first one who sells coins to avoid significant capital loss.
