I want to know if by solving captchas can cause damage to your brain. I googled a bit and all sort of things came up. I like to hear opinions from people from this forum as I know a lot of persons use them here.
It's not much I make with them but 2 USD per hour in bitcoin is good is about 0.0025 btc which is better than S9 miner with energy cost in my country which can produce in 24 hours 0.012 btc. With 6 hour of work I can do more. Is it bad to my brain? I am using a 40 inch Ultra 4K HD Panasonic as my monitor just for reference.
I'm not sure if it is bad for your brain or not.
On the good side: it is something that enhances the prefrontal cortex in problem solving or rememberance.
On the bad side: it is not considered healthy to use a computer screen for 6 hours in a row (that being said, if you use say 30 faucets with claims every hour and using less than 10 minutes to solve all of the captchas then it is probably fine).
Re-Captcha by Google would help the brain to anayse and problem solve. But other ones like solve-media (where letters need to be inputted) are designed to confuse so it may be unhealthy to do too many of them.
It isn't considered healthy to sit and stare at a computer screen for long periods of time but that hasn't really been conclusivley proven and is dependent on what is done).
