Here is a chart with my prediction of local bottoms and tops if we happen to be in a bear market over 2 years. I chose COINBASE:MKRUSD as my metric because its current price action resembles the empirical price data from the former bear trend. I'm not saying this prediction is certain, however this chart seems to be in a similar pattern.
I have been successful in spotting COINBASE:BTCUSD bottoms and long-term "ghost patterns" in the last 2018 Bitcoin bear market.
