How will you provide the needed security and hackers protection?
Thanks for your great question.
There are two options:
1/ you let us manage your key
2/ you manage by your self.
if you manage it by your self:
Then all transaction will be signed by your private key at client (web client or mobile client) (let check our game and using your wallet to connect)
if you let LetBet manage your key:
your key will be encrypted by your password on our cloud, and it will be only decrypted when u do login to play our game.
and again, all the game will do make a transaction to our blockchain and all transaction need to be signed by your private key at client.
We will make a detail article to explain your question, it's really great question BitByata.
