CoinAdster has paid in Bitcoin for shortlinks, a faucet and PTC ads since 2019, according to its own footer, with withdrawals to FaucetPay or your own Bitcoin wallet. Its Trustpilot profile is the most useful evidence: 2.4 out of 5 from 108 reviews, split between 49% five-star and 36% one-star. Happy reviewers report instant withdrawals as recently as September 2026. Unhappy ones report failed withdrawals, rejected FaucetPay addresses, a hacked account without two-factor authentication, and unanswered support. A long-running site that clearly pays some people, and clearly fails others. Keep balances tiny and withdraw often.
Quick Facts
How we reviewed it
We have not been paid by CoinAdster and this page has no referral link. Everything below comes from CoinAdster's public home page and its Trustpilot profile, checked on 2 November 2026. We have not signed up or withdrawn, so this review carries no score and no earnings claims. The screenshots are our own captures of the public pages.
What is CoinAdster?
CoinAdster (coinadster.com) is a Bitcoin rewards site built mostly on shortlinks: you visit short links, wait out the pages and collect a credit. It also has a faucet (one claim every five minutes) and PTC ads. Earnings are counted in "credits" or "bits", which you convert to Bitcoin and withdraw to FaucetPay or your own wallet. Registration needs a verified email.
What Trustpilot Says
CoinAdster's Trustpilot profile has been claimed since December 2019. The score is 2.4 ("Poor") from 108 reviews, only 8 of them in the last twelve months. The spread is unusually polarised: 49% five-star, 36% one-star. Nearly all are marked as unprompted, and Trustpilot adds a warning that the company "may be associated with high-risk investments".
- Praise: several reviewers report instant withdrawals, the latest in September 2026.
- Payout failures: reviewers report withdrawals that failed despite meeting the minimum, FaucetPay addresses rejected, and payments that never arrived (2023 to 2025).
- Security: one reviewer in August 2026 says they lost funds in an account hack and that there was no two-factor authentication.
- Captchas and proxy flags: reports of captcha loops, Cloudflare checks and false proxy warnings.
- Support: one says tickets went unanswered.
The company replies to many negative reviews, usually pointing to wrong addresses, shared or flagged IPs, or browser shields. Those may be right in individual cases, but a pattern of "it's your setup" replies is one to know about. Trustpilot doesn't verify these claims, so treat them as reports, not facts.
Getting Paid
- Methods: FaucetPay or your own Bitcoin wallet.
- Minimum: the home page says "low minimum" without a figure. A company reply on Trustpilot says instant payouts start at 5000 bits and requires a linked FaucetPay address.
- The "bits" problem: the site never defines its bits-to-Bitcoin rate on the public page. In its Trustpilot reply it reportedly equates 5000 bits with 500 satoshi, which isn't the usual bit (100 satoshi), so check the real minimum in your account.
For how to compare minimums and fees across sites, see our cash-out guide.
What We Couldn't Verify
- No operator, company or address on the public pages.
- Earning rates for shortlinks and the faucet aren't published, and the home page's demo balance is illustrative.
- Rules on VPNs and multiple accounts weren't visible, though Trustpilot reports aggressive proxy flags.
Shortlinks pay little and carry real annoyance cost. Our real hourly rate guide shows how to count it.

Tips if You Try It
- Use a verified FaucetPay address that is linked before you earn.
- No VPN and no browser shields on the site.
- Keep balances small and withdraw as soon as you reach the minimum.
- Use a unique password. No 2FA means a leaked password empties the account.
- Screenshot your first withdrawal in case you need support.

Final Verdict
Verdict: pays some people, fails others, so keep it tiny
CoinAdster is old enough to have a record and clearly pays some users quickly. The same record shows failed withdrawals, support gaps and a hack report with no 2FA. Treat it as a small experiment, never hold a balance there, and don't treat it as part of a daily routine.
