0.25B is $150. They are $100 per chip if you order directly from their site.
While this is true, you cannot order just one chip from Bitmine and this price covers air shipping to anywhere on the planet. So I needed a little extra to cover this expense. Thank you for your interest. Why don't you buy a chip, and check her out my friend!
Might I add if you buy 4 chips you get 1 FREE so that would roughly come out to $100 each, same as on the site but with no quantity restrictions or waiting period! Man I am just giving these things away.... Your welcome, I get more from giving than receiving anyhow..
