Features and earning opportunities
How to earn with Earn.com?
Earn.com had a paid email program where you needed to complete different steps given by the advertiser in order to earn Satoshis. The amount depended and was sometimes over $1. Rewards were also given if someone sent you a message — you could edit the amount you wanted to receive in order to start a chat with someone.
How to get verified?
Verification was required to cash out earnings. This involved connecting a LinkedIn account with 50+ friends (free and easy to create), then adding an institutional email (e.g. an official work address, not a personal one). After submitting the task, verification was instant and rewarded $1 for free.
Referral program
For every person referred to earn.com, $1 was earned once they got verified, using an affiliate link available in the dashboard.
Withdrawal
Withdrawing earnings was very fast and done automatically within an hour in most cases. The minimum requirement to cash out was only $2, with a network fee of 0.0000114 BTC. Users could choose to receive coins into their wallet or Coinbase account.
Conclusion
Earn.com was a legit program that had been doing business for over a few years before being acquired by Coinbase.
