The miners just like most of us now, just interact with some apps, do the task required by the devs and claim free coins daily ontill the project lunches, then sell off and enjoy the money. You pay nothing to get them, every free money in crypto is called AIRDROP.
You got it wrong my friend, please do more research and keep learning, this is not the explanation and meaning of mining. Interacting and doing daily tasks on a crypto app for rewards is still airdrop because you pay no money getting but doing a specific set of daily tasks for it. Airdrop are not even free, you work for it with your money or doing a simple task, two kinds. I guess you are thinking about Hamster Kombat, Blum, NOTCOIN and the rest "Tab and earn" as mining, NO. They aren't, they are airdrop by doing daily tasks. Miners are people that validate transactions on any blockchain to ensure that each transaction meets the network standard (no double spend, etc).
Op, this is the exact work of a miner not what you wrote on your post, keep learning
