Speedcoin Captcha :
Our Speedcoin Captcha will provide you with FREE Speedcoins (internet currency) each time a visitor of your website uses Speedcoin captcha on your website. You can use the Speedcoin captcha on the new user registration page of your website or on other pages where your website member needs to fill in web forms on your website, etc.
Various Captcha boxes protect websites against spam. Usually they produce a Captcha box where new users need to enter some letters.
This Speedcoin Captcha works in a different way – users of your website will see the Speedcoin Captcha box on your website page with information that they need go to Speedcoin.co, where they will FREELY obtain up to 150 Free Speedcoins .
Your user then sends a certain amount of those Speedcoins to the Speedcoin address at the Captcha box.
After our system receives these Speedcoins from your new user (it takes a few seconds only), our website will confirm to your website that your new customer is a real individual.
All speedcoins we receive from your users will be automatically forwarded to your speedcoin address. The statistics of these will appear on your website details page.
By this method you protect your website against spam bots, prevent the same user re-registering/re-filling web forms with different email addresses and at the same time you will get free Speedcoins which you later can convert to Bitcoins.
