Nope.
Sorry mate, impossible...
this is/was my old address from my multi-bit Classic Wallet
i have moved all funds as well as switched into more modern / better wallets after 2016
and burned the wallet as well for security reasons...
so this is my NEW address (since around 2018-2019) now...
For security reasons, feel free to send me a PM for extra confirmations / verifications if wanted...

1GrMF4YU8mahMKHVaWwL2Lwf5quwDwpt8A is not from multi-bit Classic Wallet.
I sold the account you use in 2017. To someone else.

This shows how a signed message can expose lies.
