All these domain sales outlets recommend the sellers use BINs, claiming you are more likely to sell the domain with a BIN. The problem for the seller, is probably it's the domains with lower BINs relative to market price which sell better than BINs with BINs higher than the market price. And with "market price" being so flexible, depending on the buyer, it's difficult to get this right. The only advice about this, is to put you BIN at a point where you would be happy to sell the domain, if it's BIN'd.
For me personally. I list all my domains at afternic and elsewhere, with 1 minimum price. For ease of establishing a minimum price. And I don't set BINs. The problem with this strategy is that not all domains are of equal value. So for some, if you set the minimum price too high, the minimum bid will be higher than the domain is probably worth and you won't get any offers, and it you set it too low, you will get a lot of low-ball offers to deal with on your best domains. Which you will soon be sick of handling. The solution, is probably to set minimum bids on domains individually. Or if that is too much work, then to classify your domains into different price ranges, and to set minimum bids for each price range.
The problem with the solution proposed in the preceding paragraph, is you are unlikely to get your pricing of each domain correct, and for those that you get incorrect, then the first paragraph comes into effect. Catch 22. So, although, it's do as I say, not do as I do. I'd recommend every domain has it's own minimum price based on a percentage of your expected sales price. If you want a percentage, I'd say between 50-80% of your expected sales price for each domain.
Buyers expect the minimum price to be at least somewhat related to your actual selling price. They get pissed off with min price of $1000, they bid $1000, and you come back with a price of $20,000. Which you can cover, if you have a BIN
