The analysis discusses the timing for exiting altcoins by examining the dominance of stablecoins USDT and USDC. It suggests that when the dominance of these stablecoins hits a certain level (referred to as a red zone), it signals a time to exit altcoins, because they are in a support zone. It also mentions using the Total 2 crypto cap (crypto cap of altcoins minus Bitcoin and Ethereum) to identify exit points. The analyst suggests that when the USDC and USDT dominance charts move down to the red zone, it indicates a period where big exits from altcoins should be considered. The time frame for the analysis is weekly.
