Account & Registration
5 Questions
Creating a cv4 account takes under two minutes. Visit cv4.bio, click the registration link, fill in your username, email address, mobile number, and preferred currency (BDT), then set a strong password. You must confirm that you are 18 or older and agree to the Terms and Conditions before your account is activated. A verification email is sent to the address you provide.
cv4 requires a government-issued photo ID to verify your identity before processing your first withdrawal. Accepted documents include your Bangladesh National Identity Card (NID), passport, or driving licence. You will also need to submit proof of address — a utility bill, bank statement, or mobile banking statement dated within the last three months is acceptable. Verification is usually completed within 24 hours of submission.
No — cv4 permits only one account per person, per household, and per device. Operating multiple accounts is a breach of the Terms and Conditions and may result in all associated accounts being permanently closed and balances being forfeited. If you have forgotten your login credentials, use the password reset function rather than registering a new account.
Click the "Forgot Password" link on the cv4 login page and enter your registered email address. A secure reset link will be sent to that email within a few minutes. Follow the link, set a new password, and log in normally. If you do not receive the email, check your spam folder or contact the support team at [email protected] for manual assistance.
To close your cv4 account, navigate to Account Settings and select the account closure option, or send a written request to [email protected] from your registered email address. Before closing, ensure all pending withdrawals have been processed and your balance is zero. If you are closing your account due to gambling concerns, consider activating self-exclusion instead, which is specifically designed to block access and pause all marketing communications.
Deposits & Withdrawals
6 Questions
Log in to cv4, go to the Deposit section, and select bKash as your payment method. Enter the deposit amount (minimum ৳200), then follow the on-screen prompts to complete the transaction via the bKash app or USSD (*247#) on your registered mobile number. Deposits via bKash are credited to your cv4 balance within seconds in most cases. Make sure the mobile number linked to your bKash wallet matches your cv4 registered number.
Nagad deposits on cv4 are processed instantly in the vast majority of cases — your balance updates within seconds of a successful Nagad transaction. In rare instances during peak hours, a brief delay of up to five minutes may occur. If your deposit has not appeared after ten minutes, contact cv4 support at [email protected] with your Nagad transaction ID and the support team will investigate and resolve it promptly.
The minimum deposit on cv4 is ৳200 across all supported mobile wallet methods, including bKash, Nagad, Rocket, and Upay. For bank transfers via Dutch-Bangla Bank, BRAC Bank, City Bank, Islami Bank, or Sonali Bank, a minimum of ৳500 typically applies due to bank processing requirements. There is no maximum deposit limit set by cv4, although your payment provider may impose its own daily or monthly transfer caps.
The minimum withdrawal on cv4 is ৳500. Withdrawals are processed to the same payment method used for your most recent deposit — if you deposited via bKash, your withdrawal will be sent to your bKash wallet. Before submitting a withdrawal, your account identity verification (KYC) must be complete; unverified accounts cannot process withdrawals. cv4 does not charge a withdrawal fee, though your payment provider may apply its own standard transfer charges.
Most cv4 withdrawals to bKash, Nagad, and Rocket wallets are processed within one to four hours during business hours (Bangladesh Standard Time, UTC+6). Bank transfer withdrawals to Dutch-Bangla Bank, BRAC Bank, or other local banks typically take one to three working days depending on the bank's internal processing schedule. During peak periods such as BPL season or major cricket tournaments, processing times may be slightly longer.
cv4 does not charge any platform-side fees on deposits or withdrawals. However, your payment provider — bKash, Nagad, Rocket, Upay, or your bank — may apply their own standard transaction charges as per their fee schedules. We recommend checking your payment provider's current fee structure directly. Currency conversion fees do not apply since all transactions at cv4 are conducted in Bangladeshi Taka (BDT).
Games & Gameplay
6 Questions
cv4 offers pre-match and live in-play betting on cricket at all levels — from Bangladesh Premier League (BPL) and Dhaka Premier League matches to international T20 World Cup, ODI series, and IPL fixtures. After logging in, navigate to the Cricket section, choose a match, and select from markets including match winner, top batsman, total runs, fall of wicket, and more. Odds are displayed in decimal format and update in real time during live matches.
cv4 covers BPL matches with an extensive range of markets including match winner, toss winner, top batsman, top bowler, total sixes, total fours, first wicket method, player run totals, partnership runs, and over-by-over run line markets. Live in-play betting is available throughout BPL matches, allowing you to place bets as the action unfolds. cv4 is one of the most comprehensive platforms for BPL and Bangladesh Tigers cricket betting available to players in the country.
Yes, cv4 is fully optimised for mobile play and runs smoothly in any modern mobile browser on Android and iOS devices — no app download is required. All slots from providers including Pragmatic Play, NetEnt, and Microgaming are mobile-compatible, and Evolution Gaming's live casino tables stream clearly on a stable mobile data connection. For the best live dealer experience, a 4G or Wi-Fi connection is recommended.
RTP varies by individual game and is set by the game provider, not by cv4. Most slots on the cv4 platform from providers such as Pragmatic Play, NetEnt, and Microgaming carry RTPs between 94% and 97%, with some titles exceeding 97%. The RTP figure for each game is typically displayed in the game's information or paytable section. A higher RTP means the game returns more to players over a large number of spins on a long-run statistical average.
cv4 exclusively partners with reputable, internationally recognised game studios whose games are developed and certified under strict fairness standards. Partners include Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi. All games use certified Random Number Generators (RNGs) to ensure that outcomes are genuinely random and not influenced by previous results. cv4 does not modify game mechanics; players experience the same independently certified titles as on any major global platform.
Yes, Rocket (Dutch-Bangla Bank Mobile Banking) is a fully supported payment method at cv4. To deposit via Rocket, select it from the payment options in the cv4 Deposit section, enter the amount, and authorise the transaction through the Rocket app or via USSD code on your registered SIM. The minimum deposit via Rocket is ৳200. Rocket withdrawals are also supported, with funds typically arriving within one to four hours of approval.
Bonuses & Promotions
4 Questions
cv4 offers a welcome bonus to new members on their first qualifying deposit. The exact bonus percentage, maximum bonus amount in BDT, and qualifying minimum deposit are displayed on the Promotions page and may vary by campaign period. Welcome bonuses at cv4 come with wagering requirements that must be met before bonus-derived winnings can be withdrawn — always read the full bonus terms before claiming to ensure you understand the conditions fully.
A wagering requirement is the number of times you must wager your bonus amount before any bonus-derived winnings become withdrawable. For example, a ৳1,000 bonus with a 20x wagering requirement means you need to place ৳20,000 in total bets using the bonus funds before a withdrawal is permitted. cv4 clearly states wagering requirements in the terms of each individual bonus offer. Not all game types contribute equally — slots typically contribute 100%, while live casino games may contribute at a lower rate.
Yes — cv4 operates a tiered VIP loyalty programme designed specifically for high-engagement players. As you play, you accumulate loyalty points that advance your tier level — each tier unlocks enhanced benefits including higher withdrawal limits, personalised bonus offers, faster withdrawal processing, and access to exclusive VIP promotions. The VIP programme is central to cv4's identity as a premium platform for dedicated players across Bangladesh.
Yes, bonuses at cv4 apply to qualifying deposits made via any supported payment method, including bKash, Nagad, Rocket, and Upay. The payment method used does not affect your eligibility for welcome or reload bonuses, provided the deposit meets the minimum qualifying amount specified in the bonus terms. Some limited-time promotions may specify a minimum deposit amount in BDT — check the current Promotions page for the precise conditions of each active offer.
