The reason MACD is not so reliable even with blue chip analysis; as seen in the graph the rising movement in the MACD indicator leads the buyer to think the price is going up and at the same time using a measuring stick it had been 50 days since the last price increase, instead of going positive like the MACD and timeline would lead one to think, the price went down really hard. A bad sign for the 100 day moving average is to see the price fall hard like Ethereum did at the 50 day.
