Surprise! It's actually a bit of a surprise for me, too. To-date, I've mostly been reluctant to open up purchases via cryptocurrency due to concerns about taxation, accounting, conversion rates, and my own lack of technical know-how.
However, there's a new player on the game store market which takes on most of these hairy details, and just pays devs like a regular storefront would, in USD. This makes it much easier for small outfits like me to handle. That new player is CoinPlay.io!
Right now, if you visit the following link, you'll have a range of payment options for buying NEO Scavenger Steam keys:

including BitCoin, DogeCoin, LiteCoin, as well as some more traditional methods like credit card and PayPal. So if you were one of those players asking for cryptocurrency support, or a player with some spare coins in need of spending, now's your chance!
I'll be updating the purchase page of bluebottlegames.com accordingly with new purchase options as soon as I get a chance.
