i find this post in Meta Section please read it Before waste your money
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.
Bitcoin Gold is a premined scamcoin, everyone knew this since day 1, but it got pumped a lot in social media, newbies saw it and newbies love free money so they got interested and bought BTC, then we got a post-fork dump, and now it's recovering again and all the idiots that bought altcoins are going to get smashed into the ground when Bitcoin hits $6200 rather soon.
Surprised to see theymos not calling BCash a straight scam too tho, but I get what he tried to say.
