You can earn credits by inviting your friends. Once your friend signs up, your friend will be rewarded with $15 credits and once he/she subscribes to a paid plan, you'll be rewarded with $30 credits. Your referral link is located on the Referral page under your account.
Also, if you'd like to invite your friend through other pages, you can easily modify the link by adding your referral code at the end of any of our page URLs.
For example, if you'd like to invite your friend to Pro Chart, simply add your referral code at the end of the URL which is https://cryptoquant.com/prochart/bitcoin?my-friend=[your code].
Please note that if there's a 'window' parameter at the end of the URL, you must add &my-friend=[your code] instead of ?my-friend=[your code]. For example, if you'd like to invite your friend through this link *https://cryptoquant.com/overview/full/172?window=day*, the referral link would be https://cryptoquant.com/overview/full/172?window=day&my-friend=[your code].
