Not a waste if you intend to visit the site and play, it's adds up and if you are lucky who knows how many folds you can make, but on the side note, it will be a waste of time if you easily lose it back
kidding aside, we all have our own opinion about captcha and whatever intention we have, BFG is giving us that extra perk to enjoy.
Adding some fun while claiming those coins from the faucet, either to save it for staking or play it for farming..
People are not really interested in "working" for money neither, we can make a lot of money by working anytime we want and that is not really a problem. I have to say that the best case in crypto is that there are multiple ways that you could make money without working.
The thing is, if we all have a job, a career, and we wear our suits or whatever and go work for someone else and earn a paycheck every month, we could live a life, sure it could be either good or bad but it would be guaranteed income and we would know how much we would make with our work.
There is absolutely nobody who got rich enough to be wealthy just by earning a salary, even CEO's of the biggest companies do not get wealthy that way, they get stocks to get rich or do not get rich at all. So that means you need to earn money even when you are sleeping and that is how you get rich. These people are looking at exactly that, sure chatting and earning is fine, do that if you want to there is nothing wrong with that, but staking and earning the same amount means I could make a profit when I am asleep, and that is the path to wealth.
