First of all, the anecdotal example you gave proves nothing. Profiting one time on a trade doesn't mean anything.
Second of all, trading is not binary like you are suggesting. It's not like your prediction is just right or wrong. you can profit on half your trades and lose on half of them, but if you only profit 5% when you're right and lose 10% when you're wrong, you're gonna lose a lot of money. Even if you are right 60% of the time, you'll lose money.
All that being said, none of this matters. You can trade crypto and profit, but if you profit less than holding then you have underperformed.
There are no "professional" crypto day traders out there who consistently beat the market. Even in other assets this is extremely rare, if it even exists. Show me a single person or example of somebody day trading and beating the market. I am certain you won't find anyone.
If you want to make real money consistently, learn to trade stocks over periods of time between roughly one and four months. That is what I do and I continually crush the market. Day trading crypto is gambling and the more you do it, the greater your chances of losing. Stock trading involves skill/knowledge and the more you do it and learn, the wealthier you will become.
You're right, anecdotal examples proves nothing, don't know why I gave one, but anyway.
For your information, there are professional day traders that operate in the stock market and make a living of it. Let's analyze your theory:
"Charts doesn't make behavior patterns that can reduce the odds of "
Ok, so the expected thing to realize is the only way of getting some profit is investing, not trading, or being lucky.
So according to your theory, if I enter in an operation, my odds of getting a profit is around 50%, only higher if I do my research and invest in a good coin that are cheaper than what's really worth (and expect to people notice that after I'm in).
The next thing to expect is that professional day traders of the stock market were either unemployed or pure scammers, because as we know, professional day traders don't necessarily look for the intrinsic value of what they're buying, mainly the price behavior in the charts.
So the profit of professional day traders should be exactly 0% in the long run, because 50% chance of profit and the 1:1 ratio would end up in nothing in the long run.
I don't have to bring proof or take all bitcoins of the market for myself to prove otherwise my points are invalid because it's not just simple as that, as I said before, with the correct technical analysis you only can reduce the odds of being wrong, not predict the future.
Annnnnndd you never drew a Fibonacci in your life to see that it works most of the time.
