Promote Instead Payment
I provide electronics projects, schematics, arduino and microcontroller source codes and firmware in my on-line store. You can promote my on-line store (https://wicard.net/projects) and share the projects in your social media (facebook, twitter, linkedin, instagram etc. with hashtags and direct links), your blog or your website instead of paying the price with the cryptocurrency.
Just click on the “Promote” button. Then you can insert the desired links to your posts and wait for the confirmation.
After the confirmation, you’ll be notified by an e-mail (check your inbox and spam/junk folder too) and then you can download the full project for free.
