It is a sign of market awareness if one can actually set goals and follow them to their logical conclusion. It is a fact that price changes in digital assets can be unpredictable therefore having a system that can operate in existing conditions is explicable. But if the big profit opportunity is not yet open, obtaining a small profit is another effective step. Unfortunately, no one knows how the market will behave in the closest future, but it still makes perfect sense to take any opportunity which is present at the moment. This attitude indicates that too we have our own style of managing the assets bearing in mind the various things that could at any given moment happen.
Those who buy and hold coins like Bitcoin, ETH, BNB, SOL on the spot and don't sell them despite being in profit can't be called greedy. But those who invest in memecoin or hyped coins to get a quick profit but don't sell them despite the profit to make more profit or those who trade futures to multiply their funds very quickly are greedy. And such greedy people can never succeed. Sometimes they profit more than the normal trading profit but when they lose it is many times more than that. This time they can never be in profit. To get good from crypto one must have patience and at the same time have good knowledge about crypto. Just having the ability to invest is not enough to succeed in crypto.
Yeah, there are actually two side of a coin, those who are holding Bitcoin, BNB, Sol, Ether etc, and refuse to sell on the spot market as you mentioned could be greedy but it depends certain reasons.
Now, besides being greedy, there are coin/tokens holders who are holding Bitcoin, Sol, BNB, Ether for long term, while there are those that are holding just for few weeks or months. These sets of holders are different on their planned profit targets.
Those who are holding for few weeks or months and refused to sell even when prices has increased might be absolutely greedy, but those holding for a year or more might not be greedy because their selling time is far away, except they start closing their positions because of fear on a continuous declining market prices.
