question Offers Above Minimum

[accuname]

What's everyone's experience with receiving offers above posted minimum on platforms like, Afternic, Sedo, Dan, etc.

Examples:
Minimum is 500, offers is 1k
Minimum is 1k, offer is 1500
Minimum is 2k, offer is 3k

Looking for any patterns in buyer behavior. Can anything be read into offers above minimum?

Are these more likely to be "one and done" offers?
