DigitalOcean offers "account credit" to their promoters. What are we gonna do with the account credit? I mean there should be a proper way (dollars) to reward the promoters like most of the companies in the industry.
One of my affiliate accounts with DigitalOcean earns more than 400 account credits. Don't you think that it is hilarious to spend all those on just a single company?
My suggestion is that you should at least introduce some type of converting system like $5 account credit = 1$ if you cannot offer the commission in US dollars.
