I've found the bitshares Dex to be full of opportunites. The ease with which you can move into and out of different currencies makes it possible to "dabble" in different coins and make adjustments in positions without the fear of being demolished by fees. I think this is a great way to get comfortable with crypto. The speed of transactions is also noticeable. After waiting 30 minutes for Bitcoin confirmations on other exchanges it's nice to see the quick transaction times hen using the bitshares dex.
