Nothing in investing is 100% certain.
There will always be indicators and strategies that seem almost magical because of their high accuracy. But even the best strategy can fail.

Those who understand this accept that they can be wrong, build their own framework, and follow it consistently.
Consistency is everything.
Others may watch a strategy work nine times in a row and start thinking:

"What if I had used 10x or 100x leverage?"
"What if I had borrowed as much as possible?"

That's when greed takes over.

They abandon their principles, take excessive risks, and lose everything on the one trade that goes wrong.
But the strategy itself may still be highly effective.
Someone who follows their rules can keep losses manageable. Someone who abandons them can lose everything.
Then comes regret.
They blame the strategy, find another indicator, follow another analyst, and repeat the same mistakes.
Eventually, they lose confidence in their own judgment.
Even when their analysis is correct, they hesitate.

Later, they think:
"If only I had bought..."
"If only I had sold..."

Those regrets create a desire to make up for missed opportunities, often leading to even bigger mistakes.
The same happens with investment styles.
During bull markets, people chase leverage and altcoin profits. During bear markets, they switch to shorting.
When those fail, they decide long-term investing or DCA must be the answer.
But when the market rallies again, those approaches suddenly feel too slow.
And the cycle repeats.

There is no perfect strategy or single right answer.
Some excel at short-term trading, others at trend following or long-term investing.
What matters is finding what works for you and having the discipline to follow it consistently.
Don't let greed, emotions, or other people's profits dictate your decisions.
A truly skilled investor isn't someone who's always right. It's someone who accepts being wrong, manages risk, and sticks to their principles.
