Welcome Guys!
I got airdrop 0,1 CAPTCHA some houres ago and in that way i discovered the site:
https://captcha-faucet.herokuapp.com/?valid=true
Where I can earn CAPTCHA tokens just for click pictures, which have letters and numbers!
This is my balance after maybe 20 minutes of farming
This balance we have in steem-engine instead after getting them on site:
That look's now the market orders
I think if you have many free time and nothing special to do, you can use this faucet to earn some tokens and then sell them on market for a steems!
