Practice JKB & market rules
Practice JKB has no cash value and cannot be withdrawn or redeemed into marketplace funds. BTS practice activity is public by default. JK Index is not affiliated with or endorsed by PSA.
Each event shows its own timing and rules. Earlier simulator events do not settle or open for official predictions. Review the event’s terms before confirming an order.
