Virtual cash services

I have been looking into using one of the virtual cash services such as Bitcoin or Kurrenci and wondered if anyone else is using them.

Are they 100% safe to use?
Is it easy to get cash transferred into your bank account?
Can they easily be added into Zen cart?
I have read conflicting reports about the commission charged, anything from 0 to 10%, so what is the true cost?
There is a Kurrenci add-on module so would that be a better option than Bitcoin?

All comments good and bad will be appreciated

Thanks for sending the link, I have already seen that and may contact the poster via PM for more info about changing the files etc.

Careful... bitcoin is a bubble just waiting to burst.

Kurrenci already has an integration with Zen Cart. It's here: http://www.zen-cart.com/downloads.php?do=file&id=1606

You can find these things by going to Plugins at the top of the page and just doing a search.
