I have been trading on the crypto exchange since 2017. At first, I traded in the spot market, but when I gained practice, I switched to futures trading. I assure you technical analysis will never allow you to clearly predict the future. In addition to Fibonacci levels, you will also master the theory of Eliot waves, time cycles, indicators and oscillators, etc. None of this will help predict the price for tomorrow, the coming week or month. However, all these tools allow you to make a trading plan and strictly adhere to it.
Well I think the whole idea is buy low and sell high, the hell of it is knowing when these two points happen, and there is actually no way of knowing (except, of course if you are a whale and in collusion with other whales). If there were a lot more people would be very wealthy today.
Yes, you are absolutely right.
