so having ICNs stored in myetherwallet gets you dividends?

If you control the private keys of that specific address on myetherwallet, YES, you should get dividends,unless there is some more drama with the ETH network and it forks again, in which case you could be getting "normal" dividends and "classic" dividends.

Then you don't need to do anything

Yes, you will get 2 bulks of dividends - one for the ICN you have on Iconomi site, and the other @your myetherwallet address.
You know that dividends are paid based on the amount of ICN each address has, right?

If you bought ICN from Kraken, move those bitches to myetherwallet

For now, you cannot move any bought ICN to the ICONOMI site.

Not been paid yet!

i move those bitches (15 ICN - to test) from kraken to myetherwallet ... so far 0 balance on myetherwallet.. i gues it need some time to get those 15ICN

The team approved that deposit into Iconomi site option will be available shortly after the platform is released

confirmation sent to your @mail address

Yes, as 5th Angel said, check your email address.

You need to confirm that you actually want to withdraw those bitches for Kraken to send them to myetherwallet.
