Hi everybody,
Yes, it sounds like a scam.. I took the risk and I am getting paid 0.3% as promised. I get paid back into my wallet, fairly simple.
I recommend you check on this site and benefit from the power of compounding. You need to have an invitation link to open your account, after you can invite other people and generate extra % per your referrals. Here is the link and a screen shot of my given earned interest.
