I do trading at TuxExchange.com ! It is the most secure exchange with a small community. It is growing and eventually will be a big player in the crypto exchanges. Check them out and trade with free DOGE to try out their platform.
Pretty low volume. I guess it works for a small account, but you can't trade much volume there. Not a huge fan of the name, either -- reminds me too much of MagicalTux. Lots of bad memories there.

What's this about free DOGE? Some promotion they ran?
Yes, it is a promotion to get users to try out their platform, which is amazingly fast and secure. I know the admins of the exchanges and they are very nice and honest people. They also had an interview about their exchange, it is on YouTube.
Do you have a link to the promotion? You can PM it to me if the link isn't allowed here. I searched around a bit, but I only saw a tweet from many months back that they were giving DOGE to new signups (if they ask in chat). Is that how it works now? How much DOGE are they giving?
