Why do you take the instant vote? Post it now and send 2 hours before the round end. So other people won't send bid if the bot is already full. If you get a vote in 2 hours nevertheless you post will be in the hot section.
You sent 50 steem and you will receive only 40 steem. You got free votes even then you will receive only 40 steem. Then tell me, sir, what benefit did you get for taking instant vote?
Booster doesn't have max bid limit so we can get a huge loss if anyone send bid in last minutes. But in other bots there is max bid limit so if we send there our post will go in the next round.
