From my understanding, dapps that are built on the EOS software have the ability to be used for free. I'm confused about the utility of the EOS tokens. Its quite vague in the website FAQ. Whats the purpose of EOS tokens, from its trading value?
The tokens are going to be somewhat like staking. The more that you hold the more of the system you get to use. If you hold 1% then you can utilize 1% of the power of the blockchain. You will be able to use more temporarily if no one else needs it.
There are some good YouTube videos were Dan explains it very well. The Devs can practice on the testnet but when it goes live they will need to hold some EOS to power their product
