Click-bait.

You did not do anything you say you did. Just another topic to promote shitcoins. One of the advantages of most blockchains and companies involved is that you can prove what it says even if it remains anonymous.

You can sign a message from a Bitcoins address that contains 500k to prove what it says. Or you can show your gains in the exchanges. Or you can show your addresses with these tokens.

There are thousands of ways to prove it. You chose none of it.
