@abh12345, I participated in this contest for the very fist time last weekend. So far, I have published just 2 posts. The fist (without a promotion in Twitter) was on Saturday, July 6: https://steemit.com/actifit/@cryptospa/actifit-cryptospa-20190706t204731479z
The second post with a promotion in my Twitter account was published on Sunday, July 7: https://steemit.com/actifit/@cryptospa/actifit-cryptospa-20190707t204319546z

So, theoretically, in the best scenario, according to the rules, I could have 2 raffle tickets: 1 for the post from July 7, and 1 for the promotion in the post from July 7.
