I have a lot of bad impressions about that wallet:
- I do not trust wallets or other services that depend on people/individuals/entities for their publicity or trust. If you want to gain trust, make everything transparent.
- You need to trust the company as they are closed source. You also need to trust that they did in the US ( intermediate code) and China correctly from an offline computer, serial number, wallet passphrase

Let's listen to what he has to say and the reason for his expectations.
Finally, the Giveaway is an indirect promotion of that wallet, as the prize will be a prepaid wallet with xx amount.
