Yes, you can buy Ethereum gas.
Ethereum gas is the fuel that enables transactions on the Ethereum network to take place. It is a unit of account that is used to pay for transaction fees, and it is also used to make sure that miners are compensated for their work in processing transactions.
The amount of gas that is required for a transaction depends on its complexity. For example, a simple transfer of ether from one address to another requires less gas than a contract deployment or a contract invocation.
When you send a transaction, you specify the gas limit and the gas price. The gas limit is the maximum amount of gas that you are willing to pay for the transaction, and the gas price is the amount of ether that you are willing to pay per unit of gas.
If the transaction fails, then all of the gas is refunded to you. If the transaction succeeds, then the miners who processed it are compensated according to the gas price that you specified.
The current average gas price is around 20 Gwei, which means that a simple transfer of ether would cost you around 0.0004 ETH (20 Gwei * 0.
You can buy Ethereum gas directly from exchanges such as Coinbase or Kraken. Alternatively, you can use a service like ShapeShift to convert other cryptocurrencies into ETH.
Once you have ETH, you can send it to an Ethereum wallet and use it to pay for transactions on the network.
