The issue is very clear from your screenshot 👇

👉 “Available Funds: 0.00 USDT”

That’s why you can’t buy NIGHT — your Spot wallet has no balance.

🔧 How to fix it

You need to add or move USDT into your Spot wallet:

✅ Option 1: Transfer from Funding/P2P wallet

Go to Wallets

Tap Transfer

From: Funding / P2P Wallet

To: Spot Wallet

Select USDT

Enter amount → Confirm

✅ Option 2: Buy USDT first (if you have none)

Go to P2P or Buy Crypto

Purchase USDT

After buying, it will go to Funding wallet

Then transfer it to Spot wallet (follow Option 1)

✅ Option 3: Deposit from another exchange/wallet

Tap Add Funds

Select Deposit

Send USDT to your Binance address

⚠️ Important

You cannot trade with 0 balance

The Buy NIGHT button may appear active, but the order won’t execute without USDT

Once you have USDT in Spot, you’ll be able to buy NIGHT instantly.
