Something that could help to avoid scamming is to have a token-based wallet. Once you start your ICO, people could fix their waves wallets to that token so there won't be any confusion about it.
Verified tokens is an useful tool and Wave team recently set to hidden all non-verified tokens in their exchange.
This is opposite of what decentralized means, having a team to decide is the definition of a central authority and that could kill this project fast.
Also I don't like the mining of this token which only gives us a ROI after almost 8 years, 1% per month means I'd only ROI after 100 months. that has a lol.
The fact that are hidden doesn't mean that they are not in the exchange. It means that if you search for a token, let's say: "mobile go" it will only show the verified token with that name. The rest "mobilegos" scams or not, will be listed but just with their ids, to avoid any confusion.
I only see benefits on that. You can still sell and buy your not verified tokens and you could lead your buyers easily.
I think decentralized in the context of a exchange means that it works on a decentralized network platform.
