Announcement on the Completion of the TQQQX Stock Split

Dear BigONE users,

BigONE has completed the TQQQX stock split and the associated asset adjustments. Deposits, withdrawals, and TQQQX/USDT trading have now resumed.

The TQQQX stock split was carried out in line with the 1-for-2 split of its underlying asset, ProShares UltraPro QQQ (TQQQ), which TQQQX tracks. The adjustments are as follows:

• Holdings: The number of TQQQX tokens held has been doubled.
• Price and cost basis: The price per token and the cost basis per token have been reduced by half.
• Total asset value: The adjustment affects only the number of tokens held and their per-token price. In theory, the total value of users' TQQQX holdings remains unchanged before and after the split.

Example:
If a user held 100 TQQQX at a price of 100 USDT per token before the split, their holdings would be adjusted as follows:

Before the split: 100 TQQQX × 100 USDT = 10,000 USDT
After the split: 200 TQQQX × 50 USDT = 10,000 USDT

Users can now deposit, withdraw, and trade TQQQX/USDT as usual.

BigONE, more than just asset security.

Regards,
BigONE Team
