Notice of Compliance with Nasdaq Listing Rule

As previously disclosed in the report on Form
6-K filed by BTC Digital Ltd. (NASDAQ: BTCT) (the “Company”) with the U.S. Securities and Exchange Commission on September
2, 2026, the Company received a deficiency letter from the Nasdaq Stock Market LLC (“Nasdaq”) on August 27, 2026 indicating
that the Company was not in compliance with Nasdaq Listing Rule 5550(a)(2) (the "Bid Price Rule") because the closing bid price
of the Company's ordinary shares (the “Ordinary Shares”) had been below US$1.00 per share for the preceding 30 consecutive
business days.
In accordance with the Nasdaq Listing Rules,
the Company had been provided a 180-calendar-day compliance period, or until February 23, 2027, to regain compliance with the Bid Price
Rule. To regain compliance, the closing bid price of the Company's Ordinary Shares was required to be at least US$1.00 per share
for a minimum of 10 consecutive business days.
On September 3, 2026, the Company received written
notice from the Nasdaq that Nasdaq staff had determined that for 10 consecutive business days, from August 20, 2026 to September 2, 2026,
the closing bid price of the Company’s Ordinary Shares was at $1.00 per share or greater. Accordingly, the Company has regained
compliance with the Bid Price Rule, and this matter is now closed.
Other Events.
On September 4, 2026, the Company issued a press
release announcing that it has regained compliance with the Bid Price Rule. A copy of the press release is attached hereto as Exhibit
99.1 to this Report on Form 6-K.

In accordance with the Nasdaq Listing Rules, the Company had been provided
a 180-calendar-day compliance period, or until February 23, 2027, to regain compliance with the Bid Price Rule. To regain compliance,
