Booster is not showing details in bottracker. So please go in transfer history and check first who have already sent a bid. And then send max suggested bid amount.
There is only 75 steem limit for getting 10% ROI in booster right now. People have already bid 90 steem in that round and then you come and bid 50 in last 2 minutes. So we get a huge loss. I think we got minus 70 ROI vote.
