Just a quick thought here.
With this free airdrop of BCH, everyone is rushing to find all their private keys to snatch the free BCH coins from.
They will send these coins to an exchange (hopefully sending the BTC elsewhere prior, to a new private key).
Most will send it all to the same exchange, to eventually dump into BTC.
If you have worked to keep your BTC split up and private, divided into many wallets and private keys, then doesn't this seems like a way to centralize an individual to all their past addresses?
I would like to hear people's thoughts on this and if anyone understands this deeper.
