Is RSI 100% accurate?

I'm curious about the accuracy of RSI. Can it really predict market movements with 100% certainty? Or are there any limitations and factors that could affect its reliability? I've heard traders swear by it, but I'm also aware that no indicator is perfect. Could you explain how accurate RSI is in practical applications and what factors might influence its accuracy? I'm eager to understand its strengths and weaknesses so I can make informed decisions when analyzing the crypto market.
