The belief of Ethereum bulls has basically collapsed, so this bear market is uncertain. Bitcoin has a strong belief in this round, with basic security at the bottom. My estimate is a minimum of 2.5w, and perhaps 3-4 w will be at the bottom (compared to 1.6w in the previous round). Of course, there is also a situation where BTC follows the gold trend, as it is currently a credit crisis in the US Treasury and gold is strengthening, while BTC can conduct some international settlements to some extent. In this situation, perhaps 5-6 million is enough - although I feel this is a bit too optimistic.
