The issue is very clear from your screenshot—you don’t have enough balance to place a trade.

What’s happening:

Your available balance (Avbl) is 0.00000361 USDT

Minimum required to buy anything is much higher

That’s why:

Max Buy = 0 NIGHT

Buy button is inactive

Why this happens:

On Spot trading:

You need a minimum order value (~5–10 USDT) for most pairs like NIGHT/USDT

Your current balance is basically zero, so the system won’t allow the trade

How to fix it:

✅ Option 1: Add funds

Go to Wallet → Deposit

Add at least 10–20 USDT to be safe

✅ Option 2: Transfer funds

If you already have crypto in:

Funding Wallet / P2P / Futures

Transfer it to Spot Wallet

✅ Option 3: Convert small balances

Use Convert / Small Balance Convert (Dust) to turn tiny coins into USDT

Quick tip:

Even if price is low (~0.036 USDT), exchanges still enforce minimum trade size, so micro amounts like yours won’t work.

If you want, I can guide you step-by-step on how to deposit or transfer funds based on what you currently have 👍
