Anyone can create a Bitcoin-derived altcoin like "Bitcoin Gold" (BTG) at any time with no cost. BTG is a scammy cash-grab with no ideology and no economic support, not something serious like Bcash was. That's not to say that it's impossible to make money by trading it, just like with other scamcoins, but I'm not going to get into the habit of writing announcements and guidance for every Bitcoin-derived scamcoin. If you want to do a dangerous replay-unprotected coin-split maneuver in order to claim tiny fractions of your BTC in airdrop value, that's on you.

I will write a guide later for B2X (split time in mid-November), which is more serious. After that, the bar is going to be awfully high to get me to announce similar things.
