I've been their member for almost 1.5 years. I tried to earn Karma to participate in token sales and when I got 2300 Karma and managed to buy allocations in 2 token sales they just closed my account without telling any particular reason: " Upon internal review, we believe your account has engaged in a prohibited use, prohibited business, or otherwise violates our Terms of Service. We regret to inform you that we can no longer provide you with access to our services. At this time, we are unable to disclose any additional details about our internal review process." What the heck .... ? I wrote them that I can prove that I'm a real person and I didn't do anything that would violate their rules. But they just send the same automatic answer.
Their service is one of the worst experiences I had. High fees, you have to earn Karma buy staking and trading and their fees are unreasonably high.
Stay away. I don't recommend this service. You'll just waste your time and your money on their commissions.
