Can ethereum break its highest record again if yes how much time it will take more
This will not happen until half an year later, when there will be planned improvements, based on the recent ethereum conference. In addition, the ether lacks marketing and advertising, as its developers do not attach any importance to this.
Many platforms pop up that seems better or too good in pr now that makes ETH dump more. But being still on top ETH can always make a way to success.
