I leave many of my BTC in trading wallet,
Why?
Trading platform would do the home works to
Find best solution.
I dont know to avoid forking with which wallet
I think the fork is not going to happen but you are making a mistake leaving your coins in an exchange they are not going to solve anything if there was a fork you should receive coins in both chains but it is possible a dishonest exchange may pocket the coins in one of the chains and gets free money that way without them having to risk their own bitcoins.
On the one hand it risky to leave coins on exchange around Aug 1st, but on the other more trading opportunities can occur from all of this BIP and SegWit stuff.
So the only question is what risks every single person is ready to take during this period.
About what risks you talk about? You need to have safe place for your bitcoin in any case. I'm not sure, but from some articles and comments looks like hard fork and splitting coins will not happen, but what is the problem to send bitcoins in some hardware wallet.
In times like this now when price is oscillating some exchange sites can crash, that happened before, advice to move coins from exchange wallet on safe place nobody should take easy, who knows what can happen in just couple days or even faster, can you see that price gone up like a storm, that is not good for everyone.
Risks: gaining profit VS keeping funds safe.
I guess its an issue for people like OP and me, "noobs" (sorry OP
) who has some small amounts of coins.
Of course its not a problem to move everything to hard wallet and wait for a couple of weeks or so.
Recent price oscillating is perfect from my point of view. I did ~15% of profit (of total deposit) for past week and consider this as good result for a guy that realized bitcoin pluses only a month ago and started trading only 2 weeks ago.
Lets say I have in total ~1.5k USD on exchange account in both USD and BTC. So for me its a matter of risks that I can/ready to face - whether to leave everything on exchange and continue trading during turbulent time aiming for additional profit or to remove coins from exchange to keep them safe.
Considering latest news I prefer additional profit from trading within next 2 weeks, but I am trying to track situation and ready to move everything from the exchange.
