Play heads or tails 5 times and there is a chance that it will come up heads 5 times. This does not mean that the result will always be heads. The same here. Sample N=3 (number of repetitions of the pattern that occurred in 2017 - rebound from 0.618 FIB) is definitely too little to draw conclusions about how accurate this indicator is. But like any good technical analysis indicator, Fibbonaci retracements have accurate data available online about the indicator's performance:
"How Accurate Are Fibonacci Retracements? Some experts believe that Fibonacci retracements can forecast about 70% of market movements, especially when a specific price point is predicted."
https://www.investopedia.com/articles/forex/11/fibonacci-rules.asp"Overall, Fibonacci retracement was accurate only 37% of the time. If you exclusively used this indicator for trading, you would have more losing trades than winners. Additionally, the golden rule of 61.8% was no more likely to be reliable than any other Fibonacci level."
https://www.liberatedstocktrader.com/how-to-use-fibonacci-retracement/In my opinion, in the case of crypto, this indicator is better than in the broader market, because price here is not influenced by non-technical factors (such as the company's financial results), so it is probably closer to 70% than 37%, but it is definitely not 100%.
Also 48k is a good target to take profit.
Do you think everything is based on technical analysis?
and history keeps repeating itself, I don't think if that's the case we should see a decline in bitcoin this month if it's based on history.
It turns out that this month and 2 months ago Bitcoin has continued to rise this year.
because this year may be different from previous years, where previously not many people or parties entered the bitcoin market, now many people know about it.
I asked ordinary people, do you know bitcoin, they answered yes, I saw it on the internet.
of course it will have a different impact, more market players will be more difficult to predict.
