can and it is not impossible for ethereum. but it won't be happening anytime soon. maybe during the next bullrun, and when that happens ethereum will reach a new ATH which is above 10k. I'm sure this and everyone will agree with me. the new ATH target is always 2x of the old one. this applies to all coins including ethereum. just look at the 2017 ethereum ATH which is 2k and the current ATH is above 4k. then where this front will be at 10k. so just wait.
