Recently activated 80,000 $BTC (worth about $8 billion) is speculated to be related to Cat of the Roast, who is Cat of the Roast?

Friedcat (real name Jiang Xinyu, English name #Friedcat), born in 1986 in Shaoyang, Hunan, is a highly talented blockchain pioneer:
Admitted to the youth class of the University of Science and Technology of China at the age of 15, obtained a master's degree at the age of 23, and then went to Yale University to pursue a doctorate.

In 2011, he got in touch with Bitcoin, and in 2012, he founded ASICMiner/Bitfountain with the #Bitcointalk 论坛以“Friedcat”身份发帖，众筹研发 # ASIC miner. His team developed the world's second Bitcoin ASIC miner, at one point controlling 42% of the global Bitcoin hash rate.

In August 2012, ASICMiner conducted an #ICO on the GLBSE exchange, with an initial share price of 0.1 BTC/share, which later rose to 3–5 BTC/share, resulting in substantial profits for investors, with Jiang Xinyu personally earning hundreds of millions of RMB.
At the end of 2014, due to the failure of the research and development of second and third generation chips and increasing market competition, the company fell into difficulties. In early 2015, Jiang Xinyu went missing, Bitfountain ceased operations, and his family reported him as missing. Subsequently, in 2015 and 2017, his related wallet addresses transferred approximately 36,000 BTC.

Kao Cat accumulated a large amount of Bitcoin during the peak period of ASICMiner, and his company and personal wallets may hold tens of thousands of BTC. The information mentions that he might own 200,000 BTC (though unverified), and the volume of 80,000 coins aligns with the scale of his wealth. In 2015 and 2017, wallets associated with Kao Cat transferred about 36,000 BTC, indicating that his digital assets still had activity after going missing. The activation of 80,000 BTC may continue this pattern.
These BTCs have been dormant for 14 years (since around 2011), highly overlapping with the active period of CatBake (2011–2014).

The disappearance of the roasted cat is a major unsolved mystery in the cryptocurrency world, with speculations including:
Retiring from the world: Possibly choosing to live in seclusion due to pressure or the accumulation of wealth.
Unexpected Incident: The Huai'an mine project failed in 2014, involving a contract dispute of 80 million yuan, which may lead to safety issues.
Other conspiracy theories: such as being plotted against by competitors or insiders, but without solid evidence.
