I am not a teacher, just a personal suggestion: immediately add margin. The current price is close to the liquidation line of 4.310.45 (with a 50x leverage, the remaining safety margin is only 1.2%). If the price rises further to above 4.300, at least 20% additional margin is required to maintain the position. Set a dynamic stop-loss and adjust the stop-loss to the 4.200 area (a drop of 1.4% from the current price) to avoid extreme fluctuations triggering forced liquidation. If you are optimistic about Ethereum's long-term trend, it is advisable to reduce leverage to below 20x and adjust the liquidation price to around 3.900.
