Minnowbooster and Smartmarket already adjust their vote size for when it's given and they do fine. It may be that the cost of votes from the dumb-bid-bots goes down a bit, because they don't. But in general the market will just recenter itself from the expectation of getting an early vote to the expectation of getting a late one, the bots will get bigger curation rewards, and they'll steem on.
I will place a gentleman's bet with you that if this goes through, in a month you will see the minimums for the big bots at 0% and the maximum's be 25 or 30% or more... maybe even as high at 50%.
I'm not clear on what these percentages are. The profitability restrictions on SteemBotTracker? I suspect @bid.bot may have killed the negative profits already anyway by making auto-bidding available to the general public, but it's also bound to bring the the price gap way down.
I'll be happy to have the negatives votes done with, there is far too much time wasted trying to make sure we don't get sucked into a bad vote... So if @bid.bot can do that, then I'm all for it! I also like they look at the post and make sure it is legit too... that is helpful as well!
