Go on the EOS website they are still having their daily token sale. So you need an ether wallet have some Ethereum and send it to 0xd0a6E6C54DbC68Db5db3A091B171A77407Ff7ccf (Don’t copy this link I could be a scammer, silly) once you have bought you need to register, to do that go to the EOS website and click register they will give you an EOS private and public key, map it to your ether address (they show you how) and presto when the blockchain hits in June you’ll have EOS on the the EOS blockchain. If you want the tokens now to trade you can claim them and use them right away. Buying from the ICO is 99% of the time cheaper than an exchange like kraken, and you normally save 10-20% on the exchange price. Peace x
