Thanks for spreading this awareness as there are many bad actors involved in such political stunts in crypto space. BGold should be fine as they are planning to have Replay protection by modifying the transaction data structure. But we need to be careful about 2x coins because they might not have Replay protection to hamper Bitcoin's image and trying to replace them with the Bitcoin.

We need to be cautious but I think best thing we could do is the following:

1. Your Bitcoins should be offline and you should have the private key.
2. Do not touch your private key until the 2x wallet is released.
3. Only when 2x wallet is released, immediately transfer a very small amount (negligible amount) of your original Bitcoins (BTC) to a new address. Assuming delays it may take time. Wait.
4. Keep watching 2x coins on 2x chain through the explorer which would be available by then.
5. Once you are sure you have the full balance on 2x chain, move all funds to new 2x address from the old address. This should be quick assuming lesser transaction than original Bitcoin.
6. Now immediately move your original Bitcoin balance to the new address where you moved the partial Bitcoins as per step 3.
7. Assuming BGold has replay protection we may either leave the BGold balance in the same address or move it to new address as per our wish.

These steps are my suggestions from the limited knowledge I have. Though do your own due diligence to make sure you are safely protecting your investments. Cheers!!!
