1. Bitcoin Gold fork is very badly prepared and (was referred as) is a joke. Information about the fork is lacking. no replay protection.
they say they have replay protection and on their website it has a check mark but they really don't. there is also an open issue for it but i don't see anything indicating them implementing it!
https://github.com/BTCGPU/BTCGPU/issues/18this is not the reason for being a joke though. replay protection can be implemented easily like BTH did. fast and clean. the reason for being a joke is the 16000 premine blocks!
2. Segwit 2x fork has no replay protection, which will cause double spending to a certain degree. This fundamentally challenges Bitcoin's principles....which is to prevent double spending utilizing Blockchain technology.
same here. implementing it is going to be easy, their view is that because they believe nobody will support the 1 MB chain anymore they don't need replay protection.
i say we have to wait and see what the real support is when the time comes. now it is all guesses. maybe by that time nobody supported the 2 MB blocks!
and replay attack is not double spending. it means if you spend coins on one chain, the same coins on another will be spent too.
3. possible Bitcoin Unlimited fork (sorry I have yet to read more about it) may cause chaos to the Bitcoin network and there may be many versions of the bitcoin blockchain....
didn't BU guys get merged with BCH guys?
in any case, the decentralized bitcoin has proven that they do not want the increase block size proposal of bitcoin unlimited. so if they go ahead with their fork it will be another BCH, not a "chaos"
Due to the above reasons, are the fundamentals of Bitcoin indeed challenged by the upcoming forks?
Many people have said that "Oh, we have survived the Bitcoin Cash fork, it will be the same this time, just HODL"
but it may seem that this time the value of Bitcoin could be really challenged?
price temporarily changing is just market reaction to a news. it can be "fork panic" or it can be "China panic" or it can be "bitfinex hack panic" or it can be "SEC denied ETF" or ..... it doesn't really matter.
as for "fundamental of bitcoin", as long as we stick to consensus and fork using that, meaning all the network agreeing to a change, any forks like BU, BCH, BTG, BXX will be altcoins like the previous 667 forks of bitcoin.
