An insider is someone who has or is likely to have crypto asset-related information.

Crypto asset-related information refers to anything having to do with undisclosed important information related to LINE BITMAX or regarding crypto assets handled or intended to be handled by LINE BITMAX, as well as information that could affect one's decision to purchase, sell, or trade crypto assets.

For example, the following types of people are likely to be insiders:

1) An issuer or manager of a crypto asset handled by LINE BITMAX

2) An associated company (as defined in article 8.8 of the "Regulation for Terminology, Forms and Preparation of Financial Statements") of a person described in 1)

3) A major shareholder of 1) or 2)

4) An officer of 1) or 2)

5) A person who formerly qualified as 4) within one year

6) A spouse or cohabitant of 4)

7) An employee of 1) or 2)

8) A major shareholder, officer, or employee who conducts crypto asset-related trading for business (regardless of registration or whether they are in Japan or abroad)

If you qualify as an insider, you cannot make transactions using crypto asset-related information. LINE BITMAX monitors for insider trading and other inappropriate transactions, and will alert or warn users if it is determined that any such activity has occurred. We also reserve the right to limit trading or cancel accounts at our discretion.

The following limits are set for buying/selling crypto assets.

Limits per transaction
For information on the limits for buying/selling crypto assets, see the following Help article.

Limits for buying/selling crypto assets

Minimum trading amount
You cannot sell your crypto assets if the amount that you hold is worth less than 1 JPY when converted to Japanese yen at the current sell price.
Note: The buy and sell prices of crypto assets on LINE BITMAX include spread (transaction costs).

Example: If you hold BTC 0.00000014 and the sell price of one BTC is JPY 5,000,000, then the amount converted into Japanese yen after the sale is calculated as BTC 0.00000014 × JPY 5,000,000 = JPY 0.7. Since the amount of BTC you hold is worth less than JPY 1, it cannot be sold.

For information on restrictions when trading KAIA, see the following page. (Only available in Japanese.)
