i got curious because in that post i saw, many said that you can earn two to three digits (in us dollars) with airdrops so how are you profitable if you have 5 tokens from airdrops and its ath reaches just about a dollar?
What post do you refer to? Please enclose the link here to make it clear.

According to my experience, it is very difficult to earn money from airdrops. Most of airdrops are scams and weak projects, I only got for cents from airdrops. In my point of view, the most recommended airdrops is the airdrop from reputable exchanges or platforms. So, be careful if those are airdrops from new projects.
5 tokens or 5 type of tokens. Make it clearer, please!
It depend on what tokens you get. If the tokens have the prices under $1, it is impossible to earn three digits. But if the price of 1 token is above $1k, you are sure to get three digits. Unfortunately, it is like impossible to get 5 tokens that worth three digits in dollars from 1 airdrop.
