I want you to look carefully on your BTC deposit address. If you noticed that there is an inconsistency when you copy paste it in notepad or anywhere, it only means there is a problem in your PC or other devices you use to make transactions (most probably it's a malware).
Base on what the customer support from Binance said to me, here are ways to prevent this.
1. install anti-virus software to scan/kill Trojan and viruses as soon as possible;
2. disable plus-in/extensions in browser, uninstall unknown software in the computer;
3. Under extreme risk situation, shall format disk and reinstall OS in the computer;
4. It is useful to seek help from information security expert;
And for securing your trading account, (there's a lot of information so I'll just send a link).

This is just one of the problems that I've encountered while depositing to a trading site. Other people might think that it is just normal to see that your BTC deposit address is having an inconsistency when being copied to another blank space.
P.S. If you have any problems regarding doing transactions, please share.
