Yep, that’s true. $20 for free. You can use them to create your desired DigitalOcean droplet and use them till your credits expire. Let’s get started now. Before proceeding, this doesn’t work on old accounts, you badly need a new account to get this, so get ready to create a new one!
DigitalOcean Promo Coupon Codes!
1) Go to Codeanywhere and sign up for a free account. Activate your account by verifying your email address first.
2) Then go to “File” > “New Connection” > “DigitalOcean”
3) You’ll get a message like “Don’t Have a DigitalOcean Account? Click below to receive a coupon for $10 in Credit.” Click on the “GET COUPON” link. That’s all. Here is your $10 DO coupon!
UPDATE: Looks like CodeAnywhere is providing just $10 coupon code at the moment.
Okay, but wait, I said $20 right? 
You just need to sign up using any of your friend’s DigitalOcean referral link, and you’ll get extra $10. Remember I said this tip/trick works only on new accounts.
So sign up using your friend’s DO referral/affiliate link! While signing up, you’ll get options to add your payment details (Credit/Debit card or PayPal), and below this, you will also have the option to add the promo code. You can enter your Codeanywhere promo code there! You’ll get a popup like this below, and after that, it’ll show “Promo code is valid” message.
You need to connect your Credit/Debit card or your PayPal account to activate the account, but they won’t charge* you for this, maybe just for verification purpose, they might charge and reverse the amount!
This is a kind of cool tweak to get good DigitalOcean credits for experimenting, I hope this is helpful to the folks who wanted to check out DigitalOcean before using it for their blogs! 
Do try this and let me know if you face any issues!
Note: Kindly don’t misuse this awesome offer by creating multiple accounts, it’s like violating something, I’m sure DigitalOcean will figure this out and cancel your account, it happens when you use the same credit/debit card again, and again…
Update 1:
If you guys are facing any issue with the promo code activation, here is a quick tip shared by our friend:
Update 2:
Kindly read their ToS agreement before proceeding, they are pretty serious with folks who misuse any sort of referral codes, this is a natural trick, so don’t misuse it in any way. And don’t use the same billing details (like your same Debit card or credit card) on multiple accounts without letting them know about this.
“Subscribers are restricted from registering multiple Accounts with the same billing details without first notifying DigitalOcean of that intent.”
“The use of referral codes by multiple Accounts having the same billing profile is not allowed.”
Your droplets or accounts could be flagged and it’ll take weeks to get a proper reply back from them, so don’t do anything which is against their terms.
