Bitcoin Gold, the Latest Bitcoin Fork, Explained (arstechnica.com)
Timothy B. Lee via Ars Technica explains Bitcoin Gold: A new cryptocurrency called Bitcoin Gold is now live on the Internet. It aims to correct what its backers see as a serious flaw in the design of the original Bitcoin. There are hundreds of cryptocurrencies on the Internet, and many of them are derived from Bitcoin in one way or another. But Bitcoin Gold -- like Bitcoin Cash, another Bitcoin spinoff that was created in August -- is different in two important ways. Bitcoin Gold is branding itself as a version of Bitcoin rather than merely new platforms derived from Bitcoin's source code. It has also chosen to retain Bitcoin's transaction history, which means that, if you owned bitcoins before the fork, you now own an equal amount of "gold" bitcoins. While Bitcoin Cash was designed to resolve Bitcoin's capacity crunch with larger blocks, Bitcoin Gold aims to tackle another of Bitcoin's perceived flaws: the increasing centralization of the mining industry that verifies and secures Bitcoin transactions.
The original vision for Bitcoin was that anyone would be able to participate in Bitcoin mining with their personal PCs, earning a bit of extra cash as they helped to support the network. But as Bitcoin became more valuable, people discovered that Bitcoin mining could be done much more efficiently with custom-built application-specific integrated circuits (ASICs). As a result, Bitcoin mining became a specialized and highly concentrated industry. The leading companies in this new industry wield a disproportionate amount of power over the Bitcoin network. Bitcoin Gold aims to dethrone these mining companies by introducing an alternative mining algorithm that's much less susceptible to ASIC-based optimization. In theory, that will allow ordinary Bitcoin Gold users to earn extra cash with their spare computing cycles, just as people could do in the early days of Bitcoin.

Pre-mine = scam. Big pre-mine = big scam.
Actually, bitcoin, litecoin, etc. is all one big scam. A currency with this much fluctuation isn't a currency. It's a penny stock. An unregulated speculative penny stock. When the bottom falls out (and it always does) there's going to more wailers and teeth nashers than ever before.
There are two types of people making money on this. The scammers at the top of the food chain, and the people selling "miners". Everyone else is just going to get screwed.

The way BC is setup and the way the algorithm is build is such that the complexity of calculation and thus the resources needed to perform it are increasing as time goes by.
That's incorrect. Bitcoin mining difficulty is dynamic and adjusts to the total hashing speed of the network. It does this by requiring a certain number of zeros in the SHA256 hash. As more miners join the network with custom ASICs that only perform this calculation, difficulty goes up, but if they leave to join another network (like Bitcoin Cash), difficulty goes down. It's got nothing to do with the complexity of the calculations are increasing.
