If you send me 0.01 ether I'll send you back 100 ETH!!! Here, see these transaction (you can look them up), I've really done this. Which is not a way this could be a scam?

A. The transactions are fake.
B. The scammer sent 0.01 ether from another account he controls, and then sent 100 ETH back. Since he controls both accounts, he only really spent the transactions' gas cost.
C. The scammer created a fungible token following the ERC-20 standard, and set the symbol for it to ETH. One hundred of those worthless tokens put together are still worthless.

Explanation:

The answer is A. The transactions can't be fake, because the blockchain is an immutable ledger. If they give you a transaction hash and you look it up and it is there, it must have really happened.
