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.
But if ethereum falls into a long bearish period and cannot recover after a few weeks or months as you say, who will compensate for the time and loss of the investors who believed in your ideas, I am not saying that there is no chance for ethereum to rise but we cannot confirm the value in crypto, the number will be different after every candle. The value of ethereum has not been low, investing in the moment is only looking for profit in the short term while bitcoin confirms the adjusted, the risk is not small for inexperienced and skilled investors
