Add Bittrex.com to Darkcoin homepage

I'm using them for a while now and so far everything was positive:

- support answers questions after a couple of hours
- deposit/withdrawal VERY fast, only limited by block confirmation times (1 for BTC, 3 for DRK)

A link to them on darkcoin.io would be nice.

(disclaimer: I'm not related to them nor do I get any money for this. Unfortunately...)

Should be fine at this point. I think DRK is assumed to be available on all exchanges at this point.

It'll be listed there soon. I've set up a very comprehensive list of exchanges for the new website (sitting at 28 currently).
