Thanks yousif1001 for this Link:

https://steemit.com/kayi/@hayt/kayi-instructions-on-changing-your-kayisats-to-kayieth

I read it all but still have questions.  

- How do I know if I own KayiSat or KayiWav?
(in my case, I just bought some "Kayi" at Cryptopia, yesterday)

- To show Tokens later, I think I'll need to add the token to MEW
What I found: https://etherscan.io/token/0xd5dccfae66c623e147fdbd0a0981ea5cc3d5c7ea?a=0x7254a3a0771345112418337033163747c785cacc
Contract Adress: 0xd5dccfae66c623e147fdbd0a0981ea5cc3d5c7ea

I guess thats the right one... What do you think?

Best regards
