I tested their testnet site out and it is pretty smooth. They instruct you step by step on how to do everything. It is a good way to get a feel for what it will be like when the mainnet is launched!

Altcoin.io had this to say about the release.....
When is the mainnet release coming?
Short answer, soon!
We’ve been receiving an incredibly large volume of support emails since we began building our decentralized >exchange. So before we launch on mainnet, we want to grow our operations team to ensure all our users feel secure >and have the support they need when using Altcoin.io.
In addition, we still have some remaining 3rd party security audits we need to finish to ensure we’re not putting our >users funds at risk. We know many of you are eager to begin trading on a mainnet version of our Atomic Swap Wallet >and we’ll keep you updated every step of the way.
I think they are on the right track and this will be the site everyone goes to for a quick trade. Especially for those hard to find coins.
