Transactions must be included in a block to be properly completed. When you send a transaction, it is broadcast to miners. Miners can then optionally include it in their next blocks. Miners will be more inclined to include your transaction if it has a higher transaction fee.

As much as I think it would be a throwback and although I believe that captchas serve a legitimate purpose that I would prefer not be broken, I suspect that someone who created a business outsourcing the solving of captchas to people in third world countries would be wildly successful.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable.  I never believe them.  If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins.  I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion.  Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice.  Don't keep coins online. Use paper or hardware wallets instead.

There are persistent rumors that spammers get users to solve captchas in exchange for free porn.

Someone could just go around kindergartens/pre-schools and SELL them access to some CAPTCHAs to solve on their website and submit answers. After trying to solve 100 CAPTCHAs a pop-up screen with their success rate would show up, maybe some funny picture to encourage them to continue.
Children would get to learn new vocabulary and learn spelling (not to mention testing their eye vision).

well, as far as I know, there's no service that does captcha solving for bitcoins, however there's services that do this legit. as a free starting point(you have to enter captchas to receive points which can be traded back for others solving your caps) I'd suppose CaptchaTrader [RefLink] for starters who have served my purposes for a long time now.

most captcha services charge less than 0.5 cents ($0.005) per correctly solved captcha. you must be REALLY bored if you want to do this.

It is pitch black. You are likely to be eaten by a grue.

no i dont really want to do it! but it can be handy sometimes that you want someone else to solve captcha.

or if it was for BTCs, and lets say you need like 0.2 more  BTC for a transaction Tongue

Several solutions available for this. Decaptcher.com was one of them, but they're in the process of moving to a new domain.

Edit: I -think- this is the new site. http://de-captcher.com/

I want to get paid for CAPTCHA solving in BTC as I wish to try out the idea.I'll only do this if I can get a reasonable to good pay for it though as I have to focus on filmmaking work and mining as well.Got to balance it all out and see what is more worthwhile for me.

As people have noted, you'll get paid barely anything, it'll be really boring, and you'll probably be helping people spam or hack.

I calculated through this:

Captchatrader pays 7 credits per solved captcha on their website.
You cash out a dollar for 1000 credits. That is 143 captchas solved per cent.
Now I dont know how many captchas you could solve in an hour..

You can both solve captchas and let others solve your captchas. I think that service is mostly used for downloading with jdownloader automatically. Its not hacking, but not exactly a sustainable business concept neither. The difference between "receive 7" and "pay 10" is what the webpage earns.

With the benefits Bitcoin has, and other sub-cent-work showing up (coinworker), I wonder if captchasolving for Bitcoin would actually work out for people?
What would you people say is the minimum per "workstep" and per hour for a business? Globally?

Many sites have image recognition technology for good % of successful captcha.
Sites like this are used a lot in SEO for forum posts, blog comments etc.

You could make a bitcoin faucet that lets people solve captchas. Mycryptcoin et al are probably doing this or a version of it Smiley
