Good questions.
- The stream/post requiring of the upvote will be the one on the date of the giveaway (May 30th). The title of the post in question will indicate it is the giveaway stream. (I only stream once a day so it is easy).
- The chat you will need to leave the keyword in is the Steemit chat. The Dlive chat isn't saved on the blockchain, so posting it on Steemit keeps your entry safe.
- To qualify you should be following me by/on the day of the contest. IF you want to follow now, that is would be awesome, but not required.
Hopefully I was able to answer your questions and if you have any more feel free to ask.
