Sun Yuchen Discusses Personal Holdings Beyond TRON, Expresses Caution on Bitcoin
In a recent interview with Jin Ming, TRON founder Sun Yuchen (Justin Sun) revealed details about his personal cryptocurrency and stock holdings outside of the TRON ecosystem. He identified Ethereum and Bitcoin as his primary allocations, alongside smaller positions in top-tier tokens with practical applications. In the stock market, his main focus is on Nvidia, with additional exposure to the Nasdaq index.
Sun Yuchen did not disclose specific amounts or percentages for his holdings, instead outlining his general investment strategy.
When asked about portfolio adjustments since the crypto market’s peak last year, Sun Yuchen stated that Ethereum, previously his largest holding, was significantly reduced. He explained that he sold off “at least eighty to ninety percent” of his Ethereum position when the price was between $3,600 and $4,000. He agreed with Jin Ming’s estimation that this occurred around November and December of the previous year.
He attributed this decision to a perceived “double top” technical pattern in Ethereum’s price chart. Sun Yuchen noted that Ethereum’s initial surge towards $4,800 was followed by a pullback, and its subsequent attempt to rally was bolstered by ETF-related buying and other market participants. He described this structure as “very fragile.”
Data from Binance shows that Ethereum reached highs of approximately $4,957 in August 2025 and $4,755 in October of the same year, before falling to a low of around $2,624 in November. As of midday on October 17th, Ethereum was trading at approximately $2,428, representing a decline of 33% to 39% from the price range where Sun Yuchen sold.
Sun Yuchen mentioned that the capital freed up from his Ethereum sales has remained in cash for nearly a year. During this period, he invested heavily in U.S. stocks, believing that capital would increasingly flow into the American market. He also reiterated in another segment of the interview that his primary DeFi mining activities continue to be on Ethereum, citing the limited liquidity on other chains as a reason for concentrating large capital on Ethereum.
Regarding Bitcoin, Sun Yuchen stated, “We did not reduce our BTC holdings,” explaining that Bitcoin is held as a foundational asset. He drew an analogy to Nvidia, which he considers his foundational holding in the AI sector, asserting he would not sell any unless he completely lost faith in AI. Jin Ming summarized this by characterizing Bitcoin as a foundational asset and Ethereum as an offensive position, a distinction Sun Yuchen affirmed.
Growing Skepticism Towards Bitcoin Amidst AI and Quantum Computing Concerns
When questioned about his outlook on Bitcoin versus Ethereum over the past two years, Sun Yuchen expressed a contrarian view, stating, “I am somewhat more bearish on Bitcoin.” His primary concerns revolve around the advancements in AI algorithms and the potential impact of “Q-Day”—the point at which quantum computers become powerful enough to break current encryption standards. He believes that many in the industry underestimate the threat this poses to Bitcoin and that the market has not yet priced in this risk.
Sun Yuchen initially estimated Q-Day to be about two years away but now believes it could occur within one to one-and-a-half years. He also pointed to progress in mathematical research by OpenAI, suggesting a possibility that Bitcoin could be compromised by traditional computing methods even before Q-Day, potentially by cracking Satoshi Nakamoto’s wallet. He also noted that many exchange wallets lack basic security protections.
Despite these concerns, Sun Yuchen continues to hold Bitcoin. His immediate plan is to secure these holdings by transferring them to new, never-before-signed addresses, effectively creating a cold storage solution. While this process is straightforward and takes only a few days, it will introduce some inconvenience in future access.
Whether he will ultimately sell his Bitcoin holdings remains to be seen, as he is now closely monitoring developments in the tech community, a shift from his previous lack of attention to this issue. He also revealed that TRON’s anti-quantum algorithm is currently running on its testnet and is slated for mainnet launch at least a year before their projected Q-Day.
Sun Yuchen indicated that his Nasdaq positions are still active, but he holds a “slightly bearish” medium-term view, though he has not yet initiated short positions. He believes that capital has become excessively concentrated, leading to inflated valuations for both the Nasdaq index and AI-related stocks. He also highlighted U.S. Treasury bonds as a significant source of capital, suggesting that high yields could prompt a return of funds from the stock market to Treasuries.
Within the AI industry, Sun Yuchen is most optimistic about real-world applications, particularly in AI-driven health management. He views memory and optical module sectors as overvalued due to excessive capital concentration, with many hardware stocks trading at valuations typically associated with software companies. He reported minimal holdings in A-shares and expressed a general lack of confidence in “old-generation assets” (a Chinese internet term for assets favored by older demographics), citing baijiu (Chinese liquor) as an example.
On October 12th, on-chain analytics platform Arkham reported that it had identified 211 addresses associated with Sun Yuchen, collectively holding approximately $2.25 billion. This included roughly 239,000 stETH (Lido’s staked Ether, valued at about $608 million) and 4,042 Bitcoin. Arkham’s figures are based on the addresses it could identify, while Sun Yuchen’s discussion in the interview pertained to his personal portfolio outside of TRON.
