It's a shame to see so many people buying Ethereum for 1300$ this year, its crazy you know, where are you guys when Ethereum was 150$ in 2020? Oh, you probably still doubting about what if, isn't it? Where were you when bitcoin was 3600$

Some people have already make 30x from different altcoins that you are now looking for because they understand how crypto works, buy low and sell high, that's the rules of the real crypto hunters. Now I'm just fearful because others are been greedy.
It's easy to say this now that we are in a bull market, but how could investors predict the future last year during a bear market that was lasting forever?
Everyone says buy low and sell high, but how do we know we are doing this right? Tomorrow the eth price can be more expensive or cheaper and only when tomorrow comes you will know if you did the right movement. So I think we can't blame anyone for not predicting the results of an unpredictable market.
