I am a trader, but I'm currently with my hands tied due to the news about the network split. I spent the whole morning reading about the supposed network split, and from what I could understand, I should leave my Bitcoins in a cold wallet to make sure I get "a copy" of both coins, and leave them until the confusion is settled, to avoid being targeted in replay attacks.
Also, from what I could gather, there could be a forced split when BTU support reaches 51%, or there could be a peaceful transition when 75% of miners signal BTU support. In the case of a peaceful transition, BTU would gradually become the new BTC, so there would be nothing to worry about. And in the case of a forced split, exchanges could immediately halt trading, I could get stuck transactions, etc.
I've been following
https://coin.dance/blocks for the last few days, and so when either "Estimated Hashrate by Bitcoin Client" or "Explicit Mining Pool Support by Proposal" reaches 51% (which one of them?), this race could immediately start, or will I have time to withdraw my coins and wait for them to be confirmed, etc.? The reason I ask this is because I prefer to keep trading instead of leaving my Bitcoins in a cold wallet, due to fear of the network split!
