Currently, for friends holding long positions on Bitcoin, please note that the stop loss is set at 70,000.

First, observe the resistance at 71,500 during the rebound. If it breaks through, continue holding. The next targets are 72,500—74,000—76,000.
If today it drops below 70,000 again and triggers your stop loss, it indicates that this wave of the market will continue to decline with a spike downward, aiming for the 69,000—68,500 range.
In this zone, you can lightly add to your long positions, and consider placing a new buy order around 66,000 to average down.
