Your issue is very clear from the screenshot — you don’t have enough USDT to buy NIGHT.

🔴 Problem

Available balance: 0.00000361 USDT

That’s basically zero

So:

Max Buy = 0 NIGHT

Buy button won’t work properly

✅ How to Fix It

You need to add USDT to your Spot wallet. Here are your options:

1. Transfer from Funding Wallet

Go to Assets → Funding

Tap Transfer

Move USDT → Spot Wallet

2. Buy USDT (if you don’t have any)

Use P2P (best in Pakistan 🇵🇰)

Or Buy Crypto → Card/Bank

3. Deposit USDT

From another wallet/exchange

Use USDT (TRC20) for low fees

⚠️ Important Note

Even after adding USDT:

You’ll need at least ~$5–$10 USDT to trade comfortably

Very tiny balances won’t execute trades due to minimum order limits

💡 Quick Summary

👉 Your Buy button issue is NOT a bug

👉 It’s because your balance is too low
