We can still earn money to the ethereum even the value is already high because it not the highest value this year because in my own opinion it will rise more than 5k dollars and if you invested today probably it will turn into 3 to 4, times your money in this year 2021 so it will grow your money but you need to ba patience in holding a coin because they have instances that price will going to dump but it will recover after few weeks or maybe days.
