To use CitiesToken, you will need to install MetaMask, a digital wallet. You will need to put money in it to make your first purchase.
For U.S. citizens only: you can buy ether (ETH) in MetaMask. ETH is a digital currency that enables our game to run.
For everyone else: you will need to purchase ETH from an exchange, and then transfer the ETH from your exchange wallet to your MetaMask wallet. Unfortunately, you cannot play CitiesToken with only an exchange account.
For U.S. citizens only: you are able to purchase ETH directly from the MetaMask wallet using the Coinbase widget. This is more convenient and doesn’t require you to create two accounts.
For everyone else: you need to buy ETH from an exchange using normal fiat currency. Copy your MetaMask address by clicking on the large ‘...’ next to your account, then select ‘Copy Address to clipboard’. Go to your exchange, click ‘Accounts’, and select your ETH Wallet and click ‘send’. Paste the MetaMask address in the box with the amount you’d like to transfer.
You need to convert your currency (e.g. USD, CAD, GBP, etc.) into ether to pay for things on our network.
1.A transaction fee . Every transaction sent to the Ethereum network requires ‘gas’; the gas fee is given to Ethereum miners.
2.To avoid the unlimited CitiesToken expanding, a cost must be Charged
‘Gas’ is a shorthand used to describe the cost of powering a transaction or contract in Ethereum, which is the blockchain network that CitiesToken is built on.
Because blockchain is decentralized, every transaction is distributed through multiple computers, not a central server. This ensures each token—in this case, each CitiesToken—is secure and unique. However, it also takes more computational power, which is covered by the cost of gas. Ethereum typically communicates this cost in gwei (1 million gwei = 1 ether/ETH).
When you want to withdraw the ETH to your Ethereum account. You can click the menu "Mytokens",then click the button "Withdraw ETH", then you can withdraw your ETH to your personal account.
However, most exchanges do let you buy ether with a credit card.
