I think you need to clarify what exactly you want to do. Myself (admittendly nota programmer) clearly did not understand what you are looking for or what purpose it would serve. :-)
Five minute coin never worked for me. It counted down from 300 seconds then did nothing but sit there. Refreshed it and same happened again.
It also deducted like 90% of the earnings on the last minute
Do you use Ad-block plus or similar? I had the same, but after disabling ABP for that site there's a link in the middle that will bring up a overlay where you enter your address and captcha.
I'd like to hear other peoples experiences with bcchanger.com . I've tried to trade twice now (using Moneybookers escrow), but one trade was rejected by the seller stating that he won't accept escrow payments even though I made that clear from the start. The second trade is still open, but after a week of waiting I doubt it will go through.
I also tried to contact the admin of the site (about other stuff), but emails have not been answered yet.
I'd be interested to hear from others who have used the platform.
