Activity examples Here, we'll illustrate the subscription process through 4 users, A, B, C, and D, in order to demonstrate OKB snapshot data and personal subscription limits. User A B C D OKB daily snapshot amount 5 50 500 2,000 Maximum number of tickets 20 200 2,000 8,000 The price of each ticket is 0.25 OKB.

Example User A, B, C, and D wish to participate in the Allotment Session. Let’s assume their OKB holding snapshots are as follows: Snapshot A B C D Minimum OKB Holding within 3-day 50 5 500 100 Average OKB Holding within 3-day 2,000 5 500 1,000 According to the table above, the allotment coefficient of user A, B, C, and D will be 20, 1, 30, and 20 respectively. Let’s say the session supply is 2,000 tokens, then the pledge of user A, B, C, and D will be 500, 50, 1,000 and 1,000 respectively.

The current mark price of "BTCUSD-20200327-6000-C" is 0.0575 BTC, while you place an order at 0.06 BTC. The mark price of BTCUSD-20200327 futures with the same expiry date is $5,900, then the OTM value is $6,000 - $5,900 = $100.

Example Users A, B, C, and D want to participate in this token sale project. Let's assume the snapshots of their OKB holdings and corresponding allotment coefficients are as follows: Snapshot A B C D Minimum OKB Holding within 3-day 50 5 500 100 Average OKB Holding within 3-day 2,000 5 500 1,000 According to the table above, the allotment coefficients of users A, B, C, and D are 1, 8, 20, and 36, respectively.
