Greetings!
I have join this client about 2 months ago. I used this one to receive my toke name GAMEX - The transaction did well but recently I got a transaction from someone which I don't know - The client notes me that there is maybe cheat on this.
I'm a fan of Waves but is there any issue on this?
As Waves Platform is an open blockchain platform which is designed for ease of use and mass adoption, any user have an opportunity to create his own custom token and distribute among Waves holders, for example. You can check whether this token was sent with one transaction or through a Mass Transfer option on the "Transactions" tab within Beta Client.
i create new address and deposite some wct and change it to btc
its accept for airdrop or i must deposite btc

We currently do not have any promotional activity for getting free tokens. You'd better wait till the official announcement of its launch and make an acquaintance with the terms though. Stay in touch!
Guys, can you recommend some good online wallet for WAVES?
Also please do not propose exchanges as WAVES wallets.

The best wallet for Waves is Waves wallet (Beta Client)
