Siacoin will undergo a hard fork upgrade tonight. What should miners do?

According to siastats.info, the fork is expected to take 13 hours, which is around 3:00 am on November 1st, Beijing time.

After this hard fork upgrade, all mainstream ASIC miners (Antminer A3, Innosilicon S11, STU-U2) can no longer mine new Siacoins, except for Obelisk's miners.

If you can’t mine new Siacoins, what can you mine?

SiaClassic (http://siaclassic.org/) will continue to maintain the original chain operation, and ASIC miners can mine SiaClassic.

Where can I mine SiaClassic?

Domestic mining pools F2Pool and CoinIn Mining Pool have both announced support for SiaClassic mining and support automatic switching without any operation by miners.
