Thanks Hive account@goldiemr... So you use vitality (hearts) to open red envelopes in world view. Hearts replenish at the rate of 1 every 2 hours. If you open enough envelopes that you run of hearts you have the option to buy diamonds via PayPal and you can then buy more hearts with diamonds. I believe there will be other functions in the future but that's all diamonds are used for right now.

So it's best to save your hearts for the Airdrops and not open too many random user envelopes in world view unless you know it's a user who drops good envelopes. Ask around in messages, people will tell you whose envelopes are good so you can look out for them. I'll post a faq in johngalt's group now also, it will answer some more beginner questions you might have.
