Hey, wondering if someone could help me out: how are the EOS tokens (currently ERC20), going to be transferred to the EOS environment, if that is what EOS is planning? how will they be used within the EOS environment?
If you're not a US resident, you can register with your Ethereum address on their site. You should keep your ERC20 EOS tokens there and once their blockchain is built, you'll get the equivalent official EOS token based on how much you have in the Ethereum address you registered with. If you are a US resident, you'll probably just need to keep your EOS tokens in a separate Ethereum wallet (not in an exchange) and once their platform is complete, they'll probably have a way to import your Ethereum address to get the equivalent tokens on their blockchain.
As far as how they're used, it's pretty much how Ether is used on the Ethereum blockchain, a way to compensate people running nodes and processing transactions on the network. And a few other things. Look at the whitepaper for details.
