You need ETH only if you want to stake. And you will want to stake if you own this token. It is no longer a limited supply coin. It is now a unlimited supply token. If you do not stake, you will lose out to inflation as more and more XGR tokens are added to the system. You can still make money with the token hopefully a lot of money but the game rules have changed.
That means when i want to stake i have to pay ETH ? or just hold it in the wallet ?
This new XGR token is a smartcontract on the Ethereum blockchain. Everytime you want to interact with the contract, like transfer (send) tokens or START to stake, you have to pay a small amount of gas (small amount of ether). Normally its like 0,001 ether/interaction or less.
If anyone want to check the status of their stake, please fell free to use Fusion Wallet which is the official wallet of GoldReserve. Even if we call it beta, you can use it to check your token or stake status (read only wallet) or you can use your private key and stake from the wallet with only one click.
