That's the one. I just bought a bunch and its already confirmed in my kucoin account. I should know. I lost an ETH worth of the wrong one first. I bought the KEY coin listed on ED and transferred it to my kucoin and it never arrived lol.
Your address is correct for SelfKey.
Why is it still relatively so cheap on ED? I thought it sold out in minutes and there is lots of hype and FOMO about this, yet 1 KEY on ED is currently about 0.065$.
