Interesting article, see where these coins are now!
If some shitty project calls its coin bitcoin, then I don't think it will greatly affect the price of bitcoin.

Not entirely accurate, since hard forks when not considered by the consensus to be Bitcoin, aren't Bitcoin. Forking Bitcoin, doesn't mean that its Bitcoin, the same as using the code Bitcoin has, to create a coin with a different name isn't Bitcoin. Its another altcoin. For example, I think you would be hard pressed to find a supporter of Bitcoin, consider Bitcoin Cash as Bitcoin.

What your really asking is will altcoins effect Bitcoin's price, and the answer is probably yes. Although, predicting how it will effect it or how it has effected it, would be difficult to measure. I would expect that the popularity of altcoins has increased exposure of Bitcoin though, and has impacted it more positively rather than negatively.

Although, it has to be said if there is a better alternative to Bitcoin, then of course it has the potential of devaluing Bitcoin. If there's a better alternative, that fixes the issues of Bitcoins, while not having any drawbacks that outweigh the positives, its quite likely that it would devalue Bitcoin. Depending on how many people would make the switch. I've said this a few times, but Bitcoin has quite a few issues which has been discussed to death, but it is currently the best out there, and eventually we might be referring to Bitcoin as the foundation that started it all, rather than the solution to the problem. There are definitely some interesting technologies, and ideas coming out of the woodwork, e.g MimbleWimble, but their current implementation isn't quite there yet.

We literally got a lot of forks already that deals with what they think is better for bitcoin. I do agree that if there are no forks around the market today then most of those market caps will go to bitcoin but it could possibly be as the same scenario that we've got today. Because there are too many altcoins that's also being chosen by many pickers that chooses altcoins aside from bitcoin. But I do not think that there's any chance that another fork will devalue bitcoin. It's like the gold that we've got in real life while we still use cash, an actual store of value just as the reason why we hold it.

They are altcoins and altcoins can not devalue Bitcoin. It does not matter only because they are Bitcoin forks.

How Many Bitcoin Forks Are There? You will be surprised!!!

In very short term, in altcoin seasons, capital can be spent to altcoins but it does not mean Bitcoin will be devalue in altcoin seasons. Bitcoin usually is sideway in altcoin seasons or it has a very good growth and is a first fire that activates altcoin seasons.

Without Bitcoin, no altcoin season so altcoins can not devalue Bitcoin.

Why would they take value out of something that already proved itself valuable amidst the ocean of copy cats? If people see value on forks, then it's good, though I don't think that the general sentiment of the market will be swayed just because one small group thinks that their forked version of bitcoin is better and more superior than that of the main one. There will surely be more forks in the future, and it is up to the public on whether they would choose it over bitcoin or not.

Just take a look at the market cap of all forked Bitcoins and you will answer your own question.
I remember that some of the big Bitcoin hardforks actually pumped the Bitcoin price,because the traders started buying more BTC,expecting to get some forked "Bitcoin" like BCH for free,and those BCH actually had some value on the market.
In the long term,more people will dump these forked "Bitcoins"(BCH/BSV) and their value will go down.
I don't see how this will devalue Bitcoin Core.
 

Unfortunately people come with politics and greed as part of their human characteristics, so Satoshi Nakamoto made provision for hard forks when those characteristics come into play. We saw how Mike Hearn and Gavin Andresen underestimated their support and they tried to take over the Bitcoin (BTC) project ...and when they failed, they created a hard fork to sabotage it and to be in control of their own copy of Bitcoin and that failed too. 

Roger Ver pushed hard to change people's perception that Bitcoin Cash was "the real"  Bitcoin and that failed too, because people quickly see through scams and trickery and enough facts are out there to discredit these claims. These Alt coins will never be "the real" Bitcoin and it is not diluting the real coin. 

I think that it won't although I think a lot of the users think so, probably because bitcoin has increased in prices even though there was a lot of bitcoin forks before we reached the current ATH.

Yes initially, fork coins will take some market value from bitcoin. The amount of market share will depend on how much hype the coin has. But after a while the market share will consolidate back into bitcoin. To further understand this phenomenon look in to bitcoin dominance and how it oscillates cyclically against altcoins including forks.

no, it will have no effect on bitcoin in the long run. although in the future there will be another hard fork and produce a new copy of bitcoin, there will be no significant impact for bitcoin development. because people prefer to hold BTC, and assume all copies are altcoins. if it is possible to devalue bitcoin, it should have happened since the first hard fork. but the reality is not like that.
