vouchers can be used to help promote
as a part of the affiliate marketing,for example: I message some guy and ask him to register under my reflink
then he messages me in game,I check if he is my ref and I send him my voucher code,he is happy,I am happy
(well if he gambles,otherwise I'm pissed cause I've wasted money,haha,but thats the risk I'm willing to take)
on the other hand,they could be used by abusers as a form of money transfer and laundering
eg: I create 100 accounts,play with faucet,convert wins to vouchers,send to one account and withdraw
so its a double edged sword
You can already send funds to other users by gifting them coins via the chat on the Crypto-Games website, so that solves your first question.
But is that really a smart idea? You would have no guarantee that you would ever make those coins back.
How to gift coins or lottery tickets to other users via chat:
The chat window allows you to tip other players by typing the command !tip [nickname] [amount] [coin]. For example, to send ChuckNorris 0.5 Litecoin to his Crypto-Games account, use the following command: !tip ChuckNorris 0.5 LTC. The minimum tipping amounts are: 0.002 Bitcoin, 0.05 Ether, 1000 Dogecoin, 0.1 Litecoin, 0.2 Monero, 0.05 Dash, 60 Gridcoin, 1 Peercoin, 1 Stratis and 1,000,000 PlayMoney.
You can buy lottery tickets for other users with the following command: !lotto [coin] [# of tickets] [nickname]. For example, to buy two Dogecoin Lottery tickets for user ChuckNorris, enter the following command: !lotto Doge 2 ChuckNorris.
You're not allowed to create 100 accounts, that's against site rules. Even with VPN's, I wouldn't even try it, if moderators see that those accounts are connected in any way, they have the right to close the accounts and take all funds from them.
From the FAQ:
Can I have multiple accounts?
-No, only one account per person is allowed. Players with multiple accounts will be blocked and all funds, including investments, will be confiscated.
