whatWhat is the cheapest way for sendingto send ether to 10 addresses? byBy using smart contract or using externallexternally owned account to send one by one...? I know that the gas limit of a normal transaction is 2100021,000...so 10 of this transaction costs 210000210,000 gas. I think send ether to 10 addresses by using smart contract hashas cost more than 210000210,000 gas, Am i right correct?
