We'll be adding coins depending on the demand for them. We may add a ShapeShift widget.
We process all payments ourselves, we do not use a third-party payment processor such as Coinpayments. This allows us to keep our money in Crypto, without losing money to fees. Unlike other companies, we're very happy to hold Cryptocurrency as our primary way of paying for our suppliers :)
STEEM and LTC are our two most-used payment methods right now. If we hear of a high demand for Dogecoin to pay for servers, then we'd be very happy to add it.
Since I'm not that big of an steem user I don't own that much Steem.
Issue with LTC (which would be my other option) is that tx fee's have been up to 1.5 USD. DOGE has stable tx fees below 0.05 USD. (only recently getting over the 0.01 USD actually)
As soon as you add DOGE I'm gonna consider using your services!
