Can you please elaborate more on this:
When you bet you don’t send money to a trusted intermediary. Instead, bets are placed by sending coins to your own addresses so that you maintain control of the private keys for your bets.
How can you ensure the clients will pay-up on their losses?
And then later I read this:
PolyCash is a platform for stablecoins and eSports betting will operate with coins pegged to the dollar. You can buy in and sell out at any time using bitcoin, but the bitcoins will be converted to dollars based on the exchange rate at the time of each transaction.
So, are the private keys mentioned previously for your own stable coin?
