Binance is the biggest and most reputable trading platform today, even I think it's worth more than Coinbase. To save your assets, you should update your password, conduct 2-layer verification, and diversify your assets, not just with BTC. You may also consider storing your property in a cold wallet or on other exchanges. Do not put all eggs in only 1 basket!
Wish your account is always safe, wish you earn a lot of profit in crypto space.
