Funny that they think he still has 10k BTC...
Do they not understand that he spent them on the pizzas???
Maybe you need to read again,
''
We’d like to offer him another chance to spend 10,000 BTC, but this time it would be deposited into our Earn Crypto service for 1 day.''
This is creative way to promote your service. But since the reward send to your service account, does that mean user is required to perform KYC?
KYC is not required!
