Actually I have 3 delegators, 50 will last in a month, another 380.. I don't know.. maybe until I can reach the 500 myself..😊 I wish. They said that they're creating minnow and it depend on me how can I optimize it.

Don't worry about self-vote😉 I stopped vote for myself since April when I joined the engagement leagues, because there's a good prize for the no-self vote account and then I learned that.. self-vote will work for me one day when I have more than 10.000 SP 😆 thank you @rudyardcatling for your information. Though my 25% still worth some value but will never use it when my VP above 80%.
