Hey!
I have the impression that hsbi as rewards are quite hot at the moment, so we'll see if this 'lottery' will attract more people or not.
About your reblog lottery, I think it's kind of vague, if you reblog, you receive some tickets for a lottery at the end of the month. In my opinion it's better to give out something every time instead of receiving tickets for a monthly on.
Besides that, I think you just need to repeat it over and over. Several people organize lotteries and nothing on Hive is built from day one.
If you want as much attention as possible, add something in your title like contest. Use appropriate hashtags like #contest or #hsbi if you give out hsbi.
Maybe try out to write an article which fits a certain community and add a contest to it, next time do it in a different community. Besides that, be active in communities, not just spitting out giveaways, but engage on others articles and join the respective discords (and chat).
In terms of rules, I prefer some 'original giveaways', not just the 'enter your name' but something more creative which keeps the bots out. In terms of prizes, I like hsbi as we all win by receiving those! :D
Hope you could get something out of this! :)
