We have been waiting for some time for the Lykke exchange to add Etherium, its a great move for them and I hope they manage to continue adding more coins, assets and currencies.  Whats nice about Lykke is they give multiple fiat pairs on every coin they add to CHF/USD/EUR/GBP/LKK

If you arent aware of Lykke its a Swiss company that has a nice semi-decentralized exchange model, I wont attempt to explain its detailed operating structure here, but the most important concepts are that your funds are in multisig wallets and you hold a private key, so unlike most exchanges your risk of the exchange or hackers taking your coins is much reduced.

The matching and actual exchanging is centralized though, and this makes the whole experience much more like a normal exchange than fully decentralized operations, in short its noob friendly.  Its also on mobile only right now (Android and iOS) with a desktop version in the roadmap.

US citizens need to wait a bit longer, this is because Lykke are taking the hard road of getting regualtory approval in many nations; in the US they have to tackle national and state regulations and I beleive that is underway.

I dont give investing advice, Im not qualified, but the roadmap for Lykke is impressive with much more than crypto trading in their vision.  Whats cool is you can buy their own crypto token LKK and own a share in the Lykke exchange, I think thats amazing.

Oh did I mention, trades are charged at 0%?  Lykke I believe intend to earn profits from consulting and platform integrations.  As always do your own due dilligence, Im not a great expert on Lykke https://www.lykke.com/city/faq
