If you buy EOS through an exchange like Kraken do you have to keep there until the ICO is over like 11 months from now? Or can you transfer it to a wallet off the exchange?
Currently you are buying an ERC20 token which you can send to an ethereum wallet. The token will be swapped for the actual EOS coin once the software is finished at the end of the ICO. So yes you can buy on Kraken or Bitfinex and send the EOS ERC20 token wherever you want to right now.
