Useful imformation again for steemians by @talanhorne sir...
This is my ideas about steem bots...I think we always check steem bot tracker before using bots..
Steembottracker makes is possible to use bots with the best chance of success. Whilst there is a lot of data presented on this page, let me show you what you need to pay attention to:

1. VOTE VALUE:
   This is the maximum amount a bot can up-vote. Note that this figure is displayed in $USD by default which can be changed to other currencies such as $SBD .

2. MIN / MAX BID
   This is the lowest amount a person can send to use a bot. For some reason it doesn't show the max bid, perhaps because most people don't set one.

3. MIN / MAX ROI.**
   This is a super important! The first number shows you how much you are are able to lose at most. If it says none it means there is NO limit as to how much you can lose rather than that you cannot lose anything! The second number is the most you are allowed to gain.

4. MIN / MAX AGE
   This is simply the amount of time that you can up-vote after you post. In most cases you have to wait at least 20 minutes before you can use a bot, and a post shouldn't be older than 3.5 days.

5. TOTAL BIDS
   This shows how many people have placed a bid on the current round of voting. It is a useful figure, but actually not necessary to look at as the next option is far better to check.

6. MAX SUGGESTED BID**
   This is also a super important field to look at! If you send more than this max suggested bid you will surely lose out. In fact you should ideally bid around 20% less or more than the suggested bid to be confidant of not losing out.

7. LAST VOTE / NEXT VOTE
   This is the amount of time until the vote happens. If you want to play it safe it is a good idea to wait until the last minutes to place a vote since you stand more chance of getting good rewards. This is because the voting is shared with everyone who bids on each round, so if you can see a good ROI when you make the bid in the final minutes it is less likely too many others will manage to place a vote as well.
   Wel done and perfect work sir...
   Happy steeming...
