They pay on average 2000 satoshi per captcha submit / faucet claim – Captcha coin gives you 0.5 CaptchaCoins; which are worth 4000 satoshi each! – so essentially you are getting 2000 satoshi for each captcha submit!
Who said that 0.5 CaptchaCoins are worth 2000 Satoshi?
Any reference for price?
https://coin-swap.net/market/CAPT/BTCHis post is a bit outdated, they're going at around 3000 satoshi each now.
