Because Coinhive has ended coin mining services, so we are replacing mining services with the beta version of WebMinePool (WMP). We have also changed the choice of Captcha from CH-Captcha to WMP-Captcha. Extra +1 ABP now is invalid for captcha service. This is the best choice for resolving captcha quickly.
Furthermore, for the calculation of point mining conversion hashrate to ABP, dynamic conversion applies following the fluctuation of mining costs and coinmarketcap digital currency rates. This dynamic conversion value has the possibility of changing every 30 minutes. If you find an error using Point Mining, please let us know so we can fix it immediately.
Currently you can use that beta service. We hope that starting April 1, 2019, this point mining feature can run smoothly.
Thank you for your attention and input from all of you. We will always update our services.
