Last night in the group, I mentioned that ETH would take profit at 4066 after breaking through. A fellow trader asked how I arrived at 4066. To be honest, it was a guess. Last month, it paused around 3068, so I determined that it would pause around 4066. I didn't say 4068; it was purely coincidental that I said 4066 because it's just a small point. Therefore, I refer to it as a 'small take-profit point.' It's not worth taking full profits on your long position below the cost of 3880. You should maintain an average cost below 3880 and wait until it breaks through 4200, at which point you can increase your position and start taking profits after pushing up another 200 points. At this point, the profits are stacked, and the average cost still holds an advantage; even a 150-point pullback won't turn into a floating loss, making the position seem quite secure. Set a breakeven stop loss, and how much you can gain depends on how things develop in the next two weeks. Why can you chase after the 4066 breakout? Because after the breakout, it surged to 4112, which is the first resistance level above 4000. Once it stabilizes here, there’s no strong resistance until 4440, making for a smooth 300-point profit. Of course, if it can't hold near 4112, it may drop back to the 4k level. So if you entered a long position above 4000, you must set a stop loss at 4000. Only when the price exceeds 4200 does it become safer; after realizing profits, set a breakeven stop loss immediately. After that, it's just a matter of how much you can harvest.
