The issue is very clear from your screenshot — you simply don’t have enough USDT to buy anything.

What’s happening:

Your available balance: 0.00000361 USDT

Minimum required to buy: much higher than that

That’s why:

Max Buy = 0 NIGHT

Buy button isn’t useful even if clickable

How to fix it:

✅ Option 1: Add USDT

Tap the “+” icon next to your balance

Deposit or buy at least 5–10 USDT (recommended minimum)

✅ Option 2: Transfer funds

If you already have money:

Go to Wallets → Funding / P2P / Earn

Transfer USDT → Spot Wallet

✅ Option 3: Sell another coin

If you hold any crypto, sell it to USDT first

Then use that USDT to buy NIGHT

Important note ⚠️

You’re trading NIGHT/USDT, and it has a Seed Tag (high risk + volatility). Make sure you:

Start with a small amount

Expect price swings
