I'm not sure about the Fibonacci levels for the cycle bottom of $ADA, but I can help you understand what Fibonacci levels are and how they are used. Fibonacci levels are a series of numbers that are derived from the Fibonacci sequence. These levels are used in technical analysis to identify potential areas of support and resistance on a price chart. The most commonly used Fibonacci levels are 23.6%, 38.2%, 50%, 61.8%, and 78.6%. These levels are used to identify potential areas where the price of an asset may reverse or consolidate. Would you like me to explain more about how Fibonacci levels work?
