Rei Kokubu's Cryptocurrency Investment Strategy: Considering the Truth About Selling Bitcoin and Future Market Trends

Self-proclaimed time traveler Rei Kokubun claims to have come from 2058. Known as a “future person” by Japanese internet users, she has gained attention after some of her past predictions proved accurate. However, currently, her investment claims regarding Bitcoin and Ethereum are sparking new debates in the cryptocurrency market.

Rei Kokubun’s Recommended Ethereum Strategy: Finding Greater Potential Than Bitcoin

According to Rei Kokubun, she purchased approximately 1,400 Ethereum in large quantities between December 2019 and early 2020, stored them in a hardware wallet, and plans to retrieve them in 2058 by burying them in her parents’ yard. What’s interesting is her reasoning for choosing Ethereum over Bitcoin.

She states that the Ethereum ecosystem offers more application opportunities and higher growth potential. In other words, her choice isn’t simply dismissing Bitcoin but a strategic decision seeking higher growth prospects.

Currently, ETH is valued at about $2,060 (as of March 2026). Considering the price movement from her purchase point to now, her strategic judgment’s success is an intriguing reference point for investors.

“Bitcoin Must Be Sold”: Interpreting Rei Kokubun’s Future Scenario

Meanwhile, Rei Kokubun makes intriguing remarks about Bitcoin’s future. She suggests that, despite Bitcoin reaching astonishing high prices, “there’s no choice but to sell, and buying becomes impossible.”

Specifically, she claims that if Bitcoin reaches 780 million yen (about $4.94 million), acquiring new units could become restricted, or Bitcoin’s inherent characteristics might no longer be suitable for trading. Currently, BTC is around $70,550 (as of March 2026), leaving significant room for further price increases.

Supporters interpret her statement as “the last chance to buy Bitcoin,” expressing excitement. However, many experts warn against this simplistic view, citing potential market speculation risks.

Validity of Past Predictions: How Credible Is Rei Kokubun?

Her followers believe in her based on some past predictions coming true—such as Japan’s Olympic gold medal counts, the March 2020 plunge of the Nikkei average, and Prime Minister Shinzo Abe’s resignation announcement in September of that year—all events that occurred later.

Critics, however, offer a different perspective. They suggest many of her predictions are likely based on extrapolations from current economic trends or political rumors at the time. There are also questions about whether her vague expressions leave room for post hoc rationalizations of “being right.”

Researchers point out that her broad claims—from earthquake forecasts to infectious disease warnings and crypto trend predictions—may involve statistical inevitability or elements of chance.

Changes in the Crypto Market Post-2024: Discrepancies Between Predictions and Reality

From 2024 onward, Bitcoin and Ethereum prices have been heavily influenced by external factors like the U.S. presidential election and ETF approval. BTC surged from around $14,000 to over $70,000, dramatically changing the market environment.

During this period, more investors have looked to her “future perspective,” but blind following has also fueled speculative fervor. Maintaining rational judgment amid market enthusiasm has become more crucial than ever.

Caution in Investment Decisions: How to Interpret Rei Kokubun’s Claims

Regardless of their truth, Rei Kokubun has sparked new discussions about crypto investments. However, financial experts consistently advise—regardless of whether future predictions are accurate—investors should first assess their risk tolerance and develop long-term asset allocation strategies.

The claim that “Bitcoin can only be sold” could trigger excessive speculation or panic selling. Historically, such absolute predictions have significantly impacted market psychology, sometimes distorting price movements.

Whether Rei Kokubun’s predictions reflect the true future or are a cleverly crafted media phenomenon, only time will tell. What is certain is that investment decisions should be based on one’s knowledge, experience, and careful risk management. Whether you believe in future voices or not, investors living in the present must rely on their judgment as their most valuable tool.
