Tomorrow key levels to watch: BTC first looks for support around $77,850. If it holds with strong volume and then reclaims $79,600–$80,000, there is a chance for a short-term rebound/repair. For resistance, watch the $81,270 intraday high. If $77,850 is broken, be prepared for a pullback into the $76,500–$75,800 area. For ETH, focus on the $2,450 level. As for altcoins, continue to primarily manage position sizing and wait for confirmation signals. The above is only a market analysis scenario and does not constitute investment advice.
