Thank you so much @paulag. This is all possible because of your generousity delegated your SP to me. By this SP delegation, I learnt a lot on how to get higher curation income. With better curation knowledge, I created a comment contest yesterday in the purpose of motivating steemian to learn "how to earn double rewards with a single upvote". However, so far nobody can answer the contest 😁😁😁. Earning double rewards by a single upvote is another technique which I discovered in my experiment to improve the curation rewards. I did not explain above because the contest is stiil running. 😁😁
