Mais HTML coins are at Yobit, and they probably won't swap...
How can I swap manually?

Probably they realized that B2X would and up being just another altcoin due to the lack of support from the Bitcoin community in accepting the SegWit2X as the real Bitcoin chain.
I think that's is very important, because it will make Bitcoin stronger, and no one else will try to change the Bitcoin protocol without consensus of the community. Miners and a few exchanges and other companies are not the owners of Bitcoin. Of course Bitcoin needs to chance, but block size is not the most important thing in Bitcoin, it is its decentralization feature.

It is hard to know whether it will be safe to transact BTC or B2X right after the fork because the lack of replay protection. Coinbase said they implemented their own replay protection in their system, but who knows whether it will work properly. Maybe the best best to do thing is to wait before doing anything.

If you are planning to move your Bitcoin to Coinbase, you can do it anytime before the hard fork. But don't leave it for the last hour, because the fork may occur before than it is planned, and Coinbase will suspend deposit and withdrawals some hours before the fork.
If I decide to sell my B2X after the fork, maybe I move my BTC there, so I can sell it as soon as possible, because looks like it will be launched with about 15% of Bitcoin price. I don't believe It will have a price higher than that soon, but I'm still not sure whether I'll hold both BTC and B2X, or whether I'll sell my B2X and buy more BTC to hold.

Thanks for the explanation. Actually, I didn't read about it because I think it's irrelevant. Maybe just another scam? It is very strange that they use the name Bitcoin in something related to ETH chain.

Maybe there's another fork coming after SegWit2x. Bitcoin Silver, but it is not relevant.
Future market for Bitcoin Silver:

Block 494,784. It is hard to say the exact day. It is expected to November 16 or 15, but it can happen before, just like for BGold fork. We have to keep our eyes on the news.

Thank you. I fixed it already. I don't know what that apostrophe was doing there.

... or three, or four, or five, or... It's hard to know how long will have to wait. Haha 

I'm not very sure about what to do, but probably I'll hold both and wait to see what is going to happen before making anything. I think it's not very safe try to sell BTC ou B2X just after the fork without knowing what could happen due to the lack of replay protection.

I also think that way, but i'm very concerned about the lack of replay protection. I fear that when I try to sell my B2X I end up losing my BTC.
I think that if B2X fails in replacing BTC, and that's what I hope to happen, the SegWit2X team will have to implement replay protection for B2X to coexist with BTC as an altcoin, because they wouldn't want their coin to die.

I would like to know what people here will do after the hard fork.

I just came here to leave my laugh.
Hahahahahahahahah
It seems that someone was wrong

It depends on what you think is a bubble is.
If you think a bubble is something that reaches a high price and suddenly loses price for any reason, than yes, it is a bubble, and "popped" a lot of times. But always started to be  inflated again and became bigger than is was before.
But if think a bubble is something that is priced higher than it should be, and it would make the bubble explode, no, it is not a bubble. I think Bitcoin can be priced a lot higher than is is right now, because just a very small fraction of world population knows about bitcoin.
Everyone knows what gold is. They know gold is a rare metal and a limited resource, but nobody knows when it will not be found anymore on gold mines, and that's what makes gold to be so valuable. But Bitcoins is more "predictable". We know that only 21 billion Bitcoins will be mined. Now, imagine what would be Bitcoin price if at least 10% of the world knew about it and wanted to have it?
Asking whether bitcoin is bubble is so nonsense as asking whether gold is a bubble, in my opinion. Bitcoin is the "new gold".

It's hard to say. I think there will be a correction, mas I don't know at what price.

I needed to change the bitcoin.conf file. Actually, I created that file with just this line:
prune=550

550 is the minimum number for pruning, if I can recall correctly. Anything below this number with result in no prune.

I think that Bitcoin will survive with or without China. If all the cryptocurrencies activities was prohibited in China, Bitcoin would still find its way to the top. Miners would move to countries where Bitcoin is legal. Japan could be the new home of big miners. 

I think it all dependes on what happens after the SegWit2x hard fork.
I hope B2X fails and keep the road free for the original and real Bitcoin go to the moon!

It is possible to prune the blockchain with Bitcoin Core Wallet. My "blocks" folder have only 511 Mb in size. It used to have 134 Gb before punning.

Muito obrigado pela resposta. Vou dar uma olhada nos de altcoins. Não tenho problema com a língua inglesa, então e não precisaria me limitar a postagens no fórum em português apenas.
Como funciona o ranking aqui do forum. Quantas postagens são necessárias para graduar, se é que é isso o que conta?
