According to Lookonchain's post, five indicators can be used to observe whether BTC has reached the top: 1. The Rainbow Chart is a long-term valuation tool that uses a logarithmic rise curve to predict BTC's potential price trend in the future. The new BTC Rainbow2023 chart shows that BTC is still cheap; 2. The Relative Strength Index (RSI) chart ≥70: BTC is in an Overbought state and may fall soon. ≤30: BTC is in an Oversold state and may pump soon. The current RSI is 61.87, and compared with previous data, BTC doesn't seem to have reached its peak yet; 3. The 200-week moving average heat map shows that the current price point is blue, which means that the price top has not been reached yet and it is a time to hold and buy; 4. The Cumulative Value Days Destroyed (CVDD) shows that when BTC touches the green line, BTC is undervalued, indicating that now is a good buying opportunity. The current CVDD shows that BTC's top has not yet been reached; 5. The Annual Average Line Multiplier shows that BTC's price is in the middle of the red and green lines. It has not yet touched the red line, and the market has not yet hit the top.
