    Sharkoin Reviews

    Sharkoin was flagged as an illegal Ponzi scheme by FoxyRating, warning users not to use it to avoid being scammed. Despite this, the site has a high user rating of 4.9/5, with some users praising its fast payouts and no fees for some cryptocurrencies. Critics label it a scam and advise against its use.

    Based on the reviews on Trustpilot, Sharkoin appears to have received mixed feedback from users. The platform has a TrustScore of 3 out of 5, with a total of 45 reviews.

    Several verified reviews highlight concerns about Sharkoin’s service. Some users, like Dipesh Pal and Atul Kumar from India, experienced issues with delayed payouts and accusations of using the platform for cryptocurrency exchange rather than gambling. Despite complaints, Sharkoin defended its practices and stated users had been warned before any account suspension.

    Mr. A from Bangladesh also criticized the platform for suspending his account and retaining his deposited money, labeling Sharkoin as a scam. The company responded by blaming the user’s violation of their terms of service.

    Although Sharkoin replies to all negative reviews typically within a month, their details have yet to be verified on Trustpilot. The platform claims to be a popular, trusted gambling site, offering instant transfers, free cashouts, and multiple deposit options. However, given the mixed user reviews, user experiences seem to be inconsistent and potentially problematic.

    SharkRoulette Reviews

    According to the Trustpilot platform, SharkRoulette has a TrustScore of 3 out of 5. As of the current period, it has a total of 59 reviews.

    Several verified reviews on Trustpilot highlight various issues with SharkRoulette:

    1. Duc Le from Vietnam rated the site 1 star and claimed it to be a scam due to his pending withdrawal request and lack of response from the support team. However, SharkRoulette argued they could not investigate without a username.
    2. Rob from Germany also gave a 1-star rating, accusing SharkRoulette of disabling his account and refusing to stop sending promotional emails, despite his account balance. SharkRoulette clarified its policy against multiple accounts and affiliate program abuse.
    3. A UK user known as “Bad luck guy” expressed disappointment with his losses on the platform and perceived it as risky.
    4. Marco from Italy rated the platform 1 star, asserting the site was rigged. SharkRoulette rebutted by emphasizing the randomness of game results and the potential impact of player strategies.

    SharkRoulette’s profile remains unverified on Trustpilot. They have responded to over half of the negative reviews, typically within a month.

    Bottom Line

    Sharkoin and SharkRoulette are online gaming platforms that allow cryptocurrency transactions.

    The platforms have received positive feedback for their simple registration, crypto variety, and quick transactions. However, they’ve also faced criticism over payout issues, account suspensions, and unsatisfactory customer service. Moreover, allegations suggest Sharkoin may be a Ponzi scheme.

    Despite their efforts to address these concerns, persisting issues and a variable TrustScore question their credibility.

    Therefore, potential users should be cautious, comprehensively research, understand the terms, and consider starting with small, affordable amounts.

    As with any financial endeavor, especially in online gambling, one should never risk more than they can afford to lose. With platforms like Sharkoin and SharkRoulette, staying informed and cautious is key to a positive experience.
