Good question....I asked Kraken support back in November and this is the response I got.

Hey There,
My name is Johnny and I'm from Kraken Client Engagement. Thank you for reaching out to us.
I bought some EOS on Kraken awhile back and I can't seem to find information about "claiming" the tokens in June 2018 once the distribution ends. Do I need to take any further action to claim the tokens I've already bought and hold in my Kraken wallet?
As far as I am aware, the tokens are yours - free and clear. There is nothing further needed on our end to verify ownership of those funds. As for converting those erc20 EOS tokens to actual EOS tokens, we have not made any announcements nor commitments to actually initiate the conversion process - so you should anticipate needing to do this yourself in case we do not intend to initiate conversions. We will make announcements on our blog and social media channels as we reach June 2018. Also feel free to open a fresh support ticket near that time to verify if what I've stated is still the case. I wish I had more details for you.
Take Care,
Johnny

Uhm..that reply was pretty clear. DO NOT keep your EOS (or any other coin for that matter), on an exchange!
Don't worry I'm not, just asking the question :)
I actually think they will reach fever pitch prices just before June, and If so i'll be selling around this time.
Thanks man!
That's just what I was looking for. They seem confident all will be well, but as @scandinavianlife says, probably best not to be holding any on Kraken (or other exchanges) around the event.
Personally I think the price will rise towards June 3rd, hopefully i'll be in at a good price and be cashing out (to buy in again later). Cheers!
Yep I have a feeling the price will be higher before June (much higher) and am kind of planning the same type of thing. Buy back in.
Cheers my friend
