What’s the reason for Bitcoin Gold’s existence? Same garbage, just a money-grabbing fork at best, an effort to steal people’s private keys at worst.

Interest has been low. That said, I think it's actually interesting. Likely to be hugely successful? Probably not.

I'm happy getting a free stake in their experiment -- decentralization is important and they're trying a different angle to achieve that.

Plus I can appreciate that it's a non-hostile fork with strong two-way replay protection and isn't trying to take Bitcoin / BTC name.

Verge, Bitcoin Gold, and Monacoin (unverified) have all been attacked in the last day or so. This is the inevitable destiny of every smaller PoW chain.

Verge and BTG were both sold as a “better bitcoin”. This is the fate of every better bitcoin.

Bgold is an altcoin not a hard fork. Hard forks are when an existing system changes (in a non-backwards compatible way). New systems are just altcoins, never hardforks. The part that confuses people is that if you attempt a hardfork without consensus, you end up with an altcoin instead.

PSA: Bitcoin Gold is a gimmick to create confusion around Bitcoin Cash. Beware of anyone peddling it.

Bitcoin Gold got 51% attacked. Miners have no issue with attacking BTG because if it dies, they could easily switch to mine another coin that also uses Equihash POW.

In all seriousness though, not all chains are equal. Have you seen the recent attacks on XVG, etc.? Not to mention BTG, Monacoin, Bytecoin, the list goes on.

The potential attack surface (you want it to be small) and cost of attacking the network (you want it to be high) are *hugely* important.

Bitcoin Gold has some of the most irresponsible/incompetent developers in all of crypto. They delegated the security entirely to 3rd party wallets, some of which stole millions and others with a history of selective scamming. They never fixed this and have no plans to.

Verge, bitcoin gold, monacoin, and now zencash have all been attacked recently because they are PoW chains that are primarily mined by GPUs. The game theory that backs bitcoin's security is broken when you can use your hardware on multiple different chains.
