Remember the Binance leak before. It is quite a reputated exchange and yet it got its users info still leaked. Just don't go in too much deeper with KYC if you know you won't even reach more than 1 BTC within your day assuming that you're day trading. I never disclosed that much info when it comes to these wide area of the market. You never know who's snooping your SMS number.
I am a verified member of binance and the reason for verification was not because I have large amount of money there but to be able to do the newly established features like margin trading, lending and IEOs. The first time I read that you must be verified before getting access to IEO participation, I rushed and did as such.
