Yes, that's a good question. Maybe it's worth it to take a bet at least 0.01, then for a long time there will be enough charge and it will be possible to support many posts of novice authors, with a minimum payout ... It is evident that there is no shortage of clients, the income will not change, but rather increase, with constant and regular transactions ...
We wanted to allow the people to gain a minimum on their publication the 0.030 or 0.060 seemed a good understood (a vote in x3 remains rare on bot steemit).
But yes, it becomes hard to keep to keep these sums.
We want to stay on a x3 because the purpose of this bot is really to help grow the community, and many young steemiant steemit leaves because it does not win anything is a problem now.
We are thinking of staying on these sums, even if it is necessary to put the bot down to recharge it, but we limit it to 4 posts per person to allow more users to benefit from this bot.
If each person helped the bot with small donation in order to increase the VP. We could advance more quickly in our project of votes to 1 $.
