Is there anyway a smart contract creator can put a limit on the gasPrice(gwei) for a transaction?

Question

I am looking at the possibility of creating a custom token on the Ethereum network & wanted to know if there is a way if i can put an limit on the gasPrice in order to prevent the so called "gas wars" ?

require(tx.gasprice < 5 * 1000000000);

From Block and transaction properties. Solidity Docs

"require(false) compiles to 0xfd which is the REVERT opcode, meaning it will refund the remaining gas." Source. – Roman Frolov Jan 31 '18 at 15:08
The transaction will be reverted to the initial state. – Roman Frolov Jan 31 '18 at 15:11
its safe to say that require(false) is equal to if(false) revert(); ? – Sujal Mandal Jan 31 '18 at 15:52

@SujalMandal yes. Solidity performs a revert operation (instruction 0xfd) in both scenarios. – Roman Frolov Jan 31 '18 at 16:00
