If only this particular post can be deleted from the forum because even though people who are in the know believes its a way to steal the entire bitcoin you have, what of those newbie coming on the forum to seek information. Someone might fall for this and there wont be anything to be done to redeem the situation.
I'm guessing, after that date, one might simply download the Coinimi wallet and import your Electrum keys into it to claim the Bitcoin Gold?
This is exactly what happened in the case of bitcoin Cash but you will have to update your app first according to that same statement you are making reference to.
