Disclaimer: I invested in the NVO crowdsale.
Waves uses a "gateway" model so trusted setup and not fully decentralized (from little I know of it). Bitshares is peer-to-peer and when I had coins in it, the problem was liquidity. Counterparty (XCP) has a decentralized exchange but is buggy and slow and has issues.
Introducing NVO, a true DEX by design from the ground up. It utilizes cryptography and the private keys are never stored on a 3rd party server, etc... Read the whitepaper. Nope, it won't be too easy. Easy is a centralized service like Ameritrade, but NVO will attempt to make it simpler by using technology and good software design. Join the slack channel to learn more.
You can purchase NVO tokens using Counterparty DEX at a lower price than the ICO as some of the "investors" are impatient and cannot wait for the launch of the wallet in 2-4 months time.
