$TUT
Greed for profit can lead a trader to ignore risks, chase rising prices, or increase position size after a quick win. In cryptocurrencies especially, this can turn an unrealized gain into a loss due to sharp volatility.

To deal with it practically:

Define in advance why you’re entering and your exit plan before placing any trade.

Don’t increase your risk size just because the market is moving strongly.

Treat potential profits as a possibility, not a guarantee.

If you feel fear of missing out, take a short pause and review your target and the acceptable loss limit.

Discipline matters more than trying to catch every move in the market.
