Talk about the trend of BTC, currently there is a rebound at the 4-hour level, but remember that a rebound is not a reversal. So the 4-hour level is still a high position to short. At the daily level, it is still bullish, and 72000-75000 is a strong support zone, so you can hold some spot. For contracts, the effective stop-loss point may be a bit lower. Therefore, it is recommended to supplement with spot.
The 4-hour level of ETH is trying to reverse, and a bullish engulfing signal has appeared, but I do not recommend everyone to speculate, as the trend is downward. Do not think about bottom-fishing, as the trend at the daily level is also downward, so ETH also advises to short on rallies.
The above is just a personal opinion; investing carries risks, and one should enter the market with caution!
