That web is legit and work?

Yes it is. Some people tried before me and I tried it. It is open since yesterday and no problem.

You can check the blockchain here :
https://blockchain.info/address/1ponziUjuCVdB167ZmTWH48AURW1vE64q?offset=0&filter=0

Every green transaction is what people send and every red transaction is people getting 120% back.

Thanks you.

There say don't use web wallets. But I can use my wallet from blockchain.info, right?
