So are you saying that if I have 10 btc in the chain-A and that chan will disappear I will not lost those chain-A~btc? I am thinking the contrary... because basically I can't move those chain-A~btc anymore (or am I wrong?). Thanks for the advice, maybe I am really wrong but this is the logic.
The chain can't disappear. People can only stop using it. If everyone comes on board the Chain B you will have your coins there as well.
This happens with just about any hard fork. This one isn't special at all, aside from the drama around it.
The coins on Chain A will always be there, but if nobody uses it then it is useless.
I think there is even a remote possibility for both chains to coexist literally forever because both are supported by parts of the community. I don't see why Bitcoin core would die as long as it has support?
It won't die so easy.
The possibility is there, but the chances are slim. If the majority jumps onto Chain B, Chain A would be risky. The difficulty would drop as it gets abandoned by miners, thus increasing the chance of a 51%.
Maybe I have used the wrong words, but I was partial correct with my logic... because if someone will buy bitcoin from the chain-A and after a couple of days nobody will continue to use that chain then he basically will lose 'money' (Fiat currency that he used to buy Chain-A~btc.).
This is one of the problem, maybe the important one because at the end it is only a question about money.

Well you are correct, however in this example (where chain A disapears) you still have your coins on chain B, which is the one that matters.
The only risk is for people who try to sell their chain B coins for chain A coins , betting chain A will succeed , but it really fails.
Yes of course, it will be one of the risk.
