Whether to go long above eth 4000 depends on whether it can break above the first resistance level of 4112-4150. If it pulls back and can hold above 3888, then if it can hold above 3888, it will attack 4500-4880 next month. So this week, after taking profits around 4k, it's best to wait and see. There are short opportunities in the range of 3930-4150, and even if the bulls are strong, they won't break through and hold immediately.
