The explanation for this forking fever is simple - new Bitcoin mining hardware like dragonmint and S9 is rolling out, and miners are creating new coins to get some profits with their old mining hardware. The guy behind Bitcoin God (ridiculous name), Chandler Guo, is not some investor, he's a pretty big miner. Bcash, the biggest fork up to this date is backed by Bitmain since the beggining.
I think it goes further than that. Bitcoin Cash is a special case. In hindsight, I believe that Bitmain created it primarily to exploit covert ASICBOOST. They spent years developing it and Segwit ruled out its use in Bitcoin.
Regarding the other forks, I think the "free money" explanation is a lot more compelling than the mining hardware explanation. Lightning-ASIC (Jack Liao) produces miners compatible with many hashing algorithms; they didn't need Bitcoin Gold for mining. What they saw was that Bitcoin Cash created a massive market cap out of thin air (without taking it from Bitcoin's market). Free money. Hence the pre-mines in a lot of these coins.
Those coins have no future and no purpose, so I would advice everyone to not buy them, and if you have a chance, dump them asap.
I wouldn't dump them ASAP. I would time your sells. Why sell Bitcoin Cash at 0.06 when you could sell it at 0.5?
