Betting Guide
On cv4 to bet How to

Sports Betting is more than just putting money on a game — it's a way to put your knowledge and passion for sport to work. Before you start betting on cv4, get familiar with the basics and you'll have a much better experience.

How to read odds

Cv4 uses decimal odds. For example, odds of 2.50 mean a ৳100 bet returns ৳250 if you win (৳150 profit). The higher the odds, the lower the chance of winning — but the bigger the reward.

Bet Types

Single bet — one bet on one event. Parlay bet — multiple events combined. Live bet — real-time betting while the match is in progress. cv4 offers all three.

Cash Out

Cash out your bet before the match ends. Use this when you're in a profitable position and lock in a guaranteed return.

Bankroll Management

Never stake more than 5%–10% of your total budget on a single bet. It's the most effective strategy for staying in the game long-term.

Technical Support
General Troubleshooting

Minor technical issues can happen from time to time. Try the steps below — they resolve most problems. If you're still having trouble, reach out to the cv4 support team.

First, make sure you're entering the correct password and that Caps Lock is off. If you've forgotten your password, use the "Forgot Password" option. If the issue persists, try clearing your browser cache or switching to incognito mode.

Check your internet connection. Refresh the browser (F5). Clear your cache and cookies. Try a different browser. If you're on mobile, switch from WiFi to mobile data or vice versa.

Wait 15 minutes first. If the deposit still hasn't arrived, contact cv4 support with your transaction ID. The support team usually resolves it within 30 minutes. Note that deposits sent from someone else's number may take longer.

Don't worry — cv4 records the exact point at which the connection dropped. When you log back in, the game should resume from where it left off. If it doesn't, contact support with the game name and the time it occurred.

On Android, enable "Install from unknown sources" (Settings > Security). Make sure your phone has enough storage. Download the APK file directly from cv4's official website. iOS users should access the cv4 website via Safari.
