Microearnings have already helped early BTC adopters to earn from zero considerable sums of money in current BTC rates. It's not always a waste of time. Sometimes there is long term potential on microearnings offers and they should be analyzed by people who are looking for opportunities and can't find them on their local communities. Each case is one case. What works for you might not work for someone else, but what works for him, might not work for you.
Therefore, I don't discourage anyone from seeking for offers, even inside the microearnings niche. The important thing is to be constantly searching something to make an income from, even when it seems nothing is going to work for you. It's necessary to be attentive to what life is bringing and trying to show. There might lie the opportunity you have been looking for, but couldn't find so far.
Maybe some people collected some sats from faucets in the yearly years and they went up x1000, but they would have been much richer if they went and found a job, even for a day or two, and used the earning to invest in Bitcoin. Those microearning yielded less than a dollar per hour, while in real life you can make at least a few dollars per hour.
The only argument is that someone had zero earning opportunities, but I don't believe a lot of people are in that position, especially in the age of Internet when you can do something online.
