1 vote is 4.9$
Many people will use this service, so let's count 4.5$ x 2 = 9$/day.
9x0.75= 6.75$ / day of net earnings, cause 25% goes to curation.
6.75x7 = 47.5$
Pay 55$ for 47$ return = 8$ loss :)
ps. a 4.5$ upvote is not useful to go on hot page.
Yes 1 vote is worth $4.9 due to account is at 85% vote power right now hence the 2 per 24 hour post. It will start at 100%.
There are only 7 spots available. There is no worry on the amount of people.
The 25% curation is only when voted at mins 20-30.
If it is with in 2-3 the author gets more of the reward.
