In this post, I will introduce the business philosophy adopted by 
Slim Whale is the silly name I have given to my bidding bot. There are so many variations of the name whale out there, I wonder if we will ever run out 馃榿 Like most of you guys out there, I am trying to find my niche here on steemit, I have posted in lots of categories, sports, utopian and some crypto posts. Since the very beginning, I have used bidding bots to raise the profile of my posts and to gain something extra on the side. I knew I wanted to own a bot and the result is
The ideea is pretty simple and I am pretty sure most of you are familiar with how this works. Every 2.4h, the bot collects bids, a bid pool is formed and when the voting power reaches 100%, votes are distributed proportional to the bids. So, for example is the total bid pool is 1 SBD, and your bid is 0.2, then you receive a 20% vote. Depending on the round, a bid can have a positive ROI (the bid pool is smaller then the bot's vote value), a negative ROI (the bid pool is too big) or a neutral ROI of 0, when the bid pool size is perfectly matched with the bot's vote value.
I want to start by listing some of the current shortcomings and then expend on the whole ROI thing.
In the current form, in almost every bidding round out, there is a losing party. If the ROI is negative, than all the participants in that round lose money. Sure, they get some publicity for their post, but giving away hard earned SBD/STEEM is not fun. If the ROI is positive, then the bot owner and all the delegators miss out, basically giving away money and free publicity. So yeah, in this current system, bidding is pretty much gambling, a lot of bids come at the last second and a lot of people are pissed, rightly so.
In my opinion, the key to improving bid bots is to make that ROI = 0, for all bidding rounds. This way, we create a fair system for all. The bidders get free publicity and the bot makes the most out of its vote. There are two bot characteristics in place right now, that can make this a reality, thanks to the features implemented by 
The ROI limit is a mechanism which in theory protects bidders from losing money in a bidding round. So, if a bot has a setting of -10% ROI limit, than the bidding pool value is capped in a way that ensures each bidder loses at most 10%. This percentage varies, some bots have it set of -40%, some at positive values, 1%, 2% and others have no protection at all.
At the moment, if you bid and your bid makes the ROI go under the limit, you will receive a vote in the next round. Seems like a perfectly good mechanism right?? Well, it's really not.馃槄 Let's say you have a bot which has an ROI limit of 0% and a voting value which insures a max profitable bid of 1 SBD. Let's say the current round is full, you bid 0.8 SBD. Another bidder places a bid of 0.3 SBD, which also goes to the next round. So, what happens in the next round? You have 2 bids, totaling 1.1 SBD and the bot max profitable bid is 1 SBD. Where is the 0% ROI limit that was promised? I'll tell where, it's gone, there is no limit. This is just a use case which will need to be addressed by
That last one advetises a -10%, but still, -82%... The solution? At the moment, this is just a matter of
Another use case which can rander ROI limits useless is bot owner's honesty. In the steembottracker, as a bot owner, you can put one limit in the config and your bot can have totally different running parameters. So for example, one can advertise a 0% ROI limit on the website and his actual bot can have no limit, or a much smaller one. I chose to believe no one does this, as this would be a total betrayal of trust and would merit expulsion from steembottracker altogether.
I go into some detail about this feature in my last post, here. This is a bot owner protection feature. Let's say for a round the bid pool is small, giving each bidder an ROI which is above the Max ROI set. In this case, the bot adjusts the vote weights, giving each bidder a vote with capped ROI. If you go on steembottracker bot details, you can already see some bots which have already set a max ROI for their bots. For a representative example, let's say you have a max ROI of 0% and the bot steem power allows for a max voting pool value to be at 1 SBD. In some round, let's assume we have 5 bidders, each with a 0.1 SBD bid for a total bidding pool of 0.5 SBD. In the old format, with no max ROI, each bidder would receive a 20% vote. In the new format, if the bot has a max ROI of 0%, each voter would receive a 10% vote. This would consume 1% of the bot voting power, allowing it to vote again in 1.2h.
Now that I have explained both ROI limit and max ROI, I hope you can see why I propose both these features be set to 0. In this scenario, bot users gain free publicity and bot owners/delegators make the most out of their steem power. A huge bonus would be bot usability. Assuring a 0% ROI would eliminate last second bidding. Yep, that's right. If a bot can guarantee this 0% ROI, it would eliminate the gambling aspects of bid voting bots. A user can simply pick a bot and bid, being sure he will receive a vote of equal value. So, no more wasting time on steembottracker, hunting bargains, which most of the time are ruined by last second bidders, or by uninformed bidders which over bid.
@slimwhale, which is championing this approachI am 
@slimwhaleI talk about investing in both my previous posts, here and here. At the moment,
Well guys and gals, I just presented you with what I believe is a fair system for bid voting bots. I paint quite a different picture compared to the classic bid voting bot, which I believe to be an imperfect system. I eagerly expect your views. Would you use a bot which guarantees this 0% ROI?
