Answer 1

Your transfer is transferring from the contract to the contract. It's not needed, and you can just delete it:

function storeETH() payable public {    
    // nothing to do here
}

Answer 2

All you need is a payable function in your smart contract. Smart contracts can act as wallets and store ETH. You will want to create a function to send ETH out of your wallet to your own wallet to get it out as well!

Answer 3

I would suggest doing this. By this, you can just send ether to the smart contract address and that ether will be get stored in the smart contract and also you can call the storeETH function. Include both functions.

function storeETH() payable public {    
// nothing to do here
}
function() payable public {}
