Staking 100k of Hive really takes courage. Just imagine that you have just placed it in a fixed deposit but it allows you to earn daily income when you support quality post with your upvote. Upvote a post after 5 min will allow you to earn 100% of the curation reward. A post reward is divided into 50% for author and 50% for curators(Those who upvote the post). Upvoting the post does not need to be 100% as it will reduce your manna which takes time to recharge. Some info for you which you can read more in the FAQ. https://hive.blog/faq.html#How_is_the_reward_pool_split_between_authors_and_curators
