You open your portfolio. Everything is green. A friend texts, “Should I buy more?” Your finger hovers over the buy button.
That feeling is exactly what this quarter created. Ethereum had its best third quarter ever. Bitcoin had its second best since 2013. Bitcoin moved from about $58.5K to near $84K in just three months.
Here is the part most people miss. Big green quarters change behavior. After a strong run, traders stop asking, “What could go wrong?”
They start asking, “Why didn’t I buy more?“
That shift is where mistakes begin.
Think about what happens next. Position sizes grow. Rules get skipped. Traders chase whatever moved the most, which this quarter was Ethereum. Then the market cools, and those oversized trades become the biggest losses.
A record quarter does not mean the next one is safe. It also does not mean a crash is coming. It tells you the wave was big, not when it ends. Markets move in waves, and nobody rings a bell at the top.
“Good quarters don’t make you a good trader. They make bad habits feel safe. Decide your exit plan while you are calm, not while you are winning.”
Beginners usually make three errors here. They buy late because of FOMO. They add leverage because recent wins felt easy. They never plan an exit because “it only goes up.”
So ask a better question.
Would your rules still work if you had bought at the start of this quarter? What about the end?
If you can’t answer, you don’t have a strategy. You have a feeling. Feelings are expensive in crypto.
