How to choose MBT to bet?
In the top right if you just click on your bitcoin balance you should see a dropdown of all 5 Currency types. Just select MBT and it should be available.

I signed up through your link and did not receive the bonus to try out your site though... I do really like the layout and subtle theme of the site thus far though

Update*** I am stupid and was looking under the wrong coin. Thank you so much. Amazing site so far.
