We will look at the status of bidbot business in detail and check the recent significant changes.
This will help us to better understand the current status of the bidbot business, as well as the basic problems and additional problems caused by recent changes.
I analyzed the data from the start of the STEEM chain, but most of the data focuses on 2018, as the bidbot business itself is mainly expanded in 2018.

Conclusion
1. Detailed bidbot Business Status
① Daily trend of SP delegation size to bidbots
In 2018, the bidbot business grew dramatically. The amount of delegation of SP (indicated by blue bars) to bidbot was steadily increasing, reaching about 22.33 million SP at the end of the year.
However, for the continuity of the analysis, I recently calculated the above chart based on the bidbotlist of 
Looking at the daily SP delegation scale (indicated by the green bars), we can see that there was often a large amount of SP delegation. Who these people are covered separately in ②.
The number of accounts that have delegated SP to bidbots is also steadily increasing.
② Major accounts with lots of SP delegation to bidbots
The well-known freedom account topped the list with about 6 million SP bidbot.
(Including the SP delegated to ocdb, it actually increases considerably over 6 million SP.)
The second place is the blocktrades account which delegated approximately 3.12 million SP. In early January of last year, he was the first to delegate a large number of SP, which led to the beginning of the bidbot business.
In addition, frystikken, who introduces himself as a co-founder of STEEM, delegated about 700,000 SP, and even smooth witness delegated more than 700,000 SP to bidbots through smooth-a, smooth-b.
When you look at ned's remarks, "Use bidbot to promote your articles", the bidbot delegation status of key accounts in the STEEM chain, and the flow of funds in the bidbot, the bidbot is actually closer to the official business of STEEMIT, INC.
③ Current individual sizes of Bidbots
The percentage of SP delegation to the top 4 bots is 52%.(smartsteem: 15%, appreciator: 14%, therising: 13%, booster: 10%)
Other major bots are buildawhale(8%), upmewhale(7%), upme(7%), rocky1(7%).
For reference, the SP owned by the bidbot accounts was very small, mostly delegated. Please refer to the table below for the details of the current SP delegated by bidbot.
④ Trend of the proportion of reward that BIdbot business takes
The proportion of curation rewards that bidbots took (in the narrow sense) was about 20.4% on average last year and seems to be in a slightly increasing trend. At the end of the year, it was 22.4%.
Articles with the help of bidbot (in the narrow sense) got an author reward of 32.1% per annum and 34.7% at the end of the year.
This number refers to the author's reward of the articles that bidbot has voted for, not the weight taken by bidbot. It is actually a more useful number to check how much compensation is being paid to bidbot users.
In short, the author reward in the article using bidbot is 34.7% of the total, more than 1/3.
2. Recent remarkable changes
① Minor changes
- Increasing trend of delegating one account to multiple bidbots
As of the end of last year, one account has an average of 1.05 bidbots delegating SP. Perhaps there are a variety of bidbots and their expected returns are different.
- Average delegation SP per bidbot declining trend
In the early days, mass delegation of several accounts was dominant, but the average delegation SP per bidbot is declining as many accounts are delegating to a relatively small SP. It also appears to be partly due to the tendency for one account to be delegated across multiple bidbots.
② A whole new change: expansion of Vote-Selling
By approving bidbots for some use of voting rights instead of delegation, Vote-Selling is expanding because it has the advantage of being able to vote directly from time to time, while generating similar profits to those that actually delegate SP.
This is a very important change. If this is enlarged, it will be very difficult to verify that the post is using the bidbot.
It is estimated that the specific bidbot's share of income earned from Vote-Selling is close to 40%. The size of Vote-Selling is also increasing with the growth of the bidbot business.
All figures in this article are accurate, but not as accurate as the above estimate of about 40%.
To make an estimate, if a particular account did not delegate an SP to this bidbot, but bidbot sent an amount in excess of 0.01 to that account, it was assumed to be Vote-Selling and the duplicate amount was removed. However, due to the incompleteness of the STEEM memo, the error may be mixed.
More importantly, the size of Vote-Selling is increasing, and this is not captured by the usual bidbot statistics to date. Given this, we can see that the bitbot business actually flourishes more than the bidbot business in the narrow sense.
③ Whatever the name, the bidbot-like scheme (in a broad sense) is also on the rise
Whatever its name and format, such as a ResteemBot, an account for paying membership fees, a scheme that sends a certain amount of STEEM / SBD first and receives its equivalent in voting is logically similar to the bidbot business in the narrow sense.
Also, the schemes to vote for a value similar to the bidbot in proportion to the SP delegated by the non-existent Dapp seem essentially the same.
In this way, the proportion of the reward that takes away from the bidbot-like business of Vote-Selling and whatever its name seems to be quite large. If all of the bidbots are running the Vote-Selling system in full swing, the impact will not be negligible.
3. Conclusion
※ This article is mainly aimed at checking detailed statistics about bidbot business. The following conclusions are included in a temporary opinion of an individual.
① Proof-of-Brain or Power-of-Bid(bot), that is the question
The narrow bidbot business takes more than 20% of the curation reward, and the reward share of the articles using the bidbot is already more than one third.
Moreover, there are a lot of articles that use bidbot (in broad sense) recently. There are many articles that use Vote-Selling, which is difficult to know whether to use bidbots or not. In sum, the articles that account for up to 4 ~ 50% of the total author reward are directly or indirectly the bidbot effect.
Even most Dapps are in the process of blacklisting and sharing to filter out bidbot users in a harsh situation with only development progress.
Looking at the present, STEEMIT's philosophy is no longer a PoB system as an abbreviation of Proof of Brain, but a PoB scheme as an abbreviation for Power of Bid (bot) may be more appropriate.
In fact, the rewards of a STEEM chain are like a kind of well that should be paid to those contributing to the value creation of the STEEM chain.
The more we give to those who pay some extra costs for our wells, such as through bidbots, the fewer rewards will be paid to those who contribute to the value creation of the STEEM chain.
As a result, STEEM chain contributors will have to slow down the rate of increase in compensation, so bidbot delegators will be able to maintain the STEEM number of returns in the short term, but the loss of the STEEM value itself is inevitable.
In addition, it creates an external diseconomy effect that leaves STEEMIT with a sense of alienation from damage to trending pages.
This has already been proven by the fact that last year's STEEM price, which had been on a continuous increase in bidbots, was much lower than the BTC decline.
The number of active users is similar at the end of 2018 or at the end of 2017, but at the end of 2017, the STEEM price averaged US $ 1, but now hovering around US $ 0.3.
If a small number of large whales and some investors focus on bidbot deleagation revenues as STEEM purchasing costs are virtually zero at present, the demand for contributions and value creation will decrease and the STEEM value will fall to the level of profitability of a normal PoS coin. It is similar to purchasing a master node.
The bidbot operators mainly focus on the "visibility" of the post as the main reason for activating the bidbot business. However, when "visibility" is required, it is extremely limited.
If we can enjoy a greater level of welfare from the perspective of the entire participant, it is a reasonable direction to go there. In the short term, there may be a decline in revenues for SP delegators, but in the long run it should be recognized that it is more beneficial to their STEEM value.
In economics, it is called Pareto improvement. Innovation is needed to ensure that more rewards are distributed fairly to the various people.
② This issue requires innovative implementation of the system
But as easy as the bidbot business, pursuing higher returns is more like human nature.
Investors who have already seen losses may have experienced some of the limitations of expanding the bidbot business, but those who enter the present price will also be easily tempted by the bidbot. It is a vicious cycle like a band of Mobius. The current STEEM price that the haircut was carried out by the collapse of the design proves it.
In the end, bidbot has come to the point that it is difficult to improve by participants' good will or future alternative.
This is one of the causes of almost all problems in the STEEM chain.
So IMO, I love the unlimited freedom and decentralization philosophy of the STEEM chain, but I think the schemes that prevent bidbots, Vote-Selling, and Circle voting should be implemented technically in a blockchain unit.
Of course, it would be difficult technically and in terms of SP stake structure.
It takes too long for new incoming users to feel all the attributes of the STEEM chain and to think and agree on it. Moreover, human thoughts are different.
If not, this problem can continue to anchor after Dapps grows.
Thank you. Be more happy in 2019.
