Whats the cheapest way to purchase GNT ? I thought about transferring ETH from coinbase to poloniex, purchase GNT on poloniex and then move it to myetherwallet but I fear the fees, I try to avoid paying more than 10% in fees for the whole process.
Please let me know if you have any recommendations

@nancybeee : It is built on Eth blockchain, I don't think that it could be the world's computer but it could at least be useful to a lot of corporations, governments, scientists an so on... In fact, it is a super computer, it uses calculation ressources but it is not about storage. It became difficult to miniaturize CPU and space is limited while companies/industries need to deal with more and more data, so Facebook could use this to process and analyse the big amounts of data they are collecting for example.
Go ahead with your idea, the fees are small on Poloniex. I think I paid 1 GNT to withdraw the token from Polo. You can also verify the fees before making the withdrawal. Your ETH fee should be low too (I don't know Coinbase but I did what you plan to do from MyEtherWallet - Polo - Exodus).
