$100 Bitcoin? Japan Post Bank's CIO Blasts 'Bubble' Value
Bitcoin's astonishing price rally this year continues to attract skeptics, including the CIO of Japan Post Bank.

Bitcoin's price rally this year continues to attract skeptics.
The latest to join the fray is Katsunori Sago, chief investment officer of Japan Post Bank, who said he believes the world's largest cryptocurrency by market capitalization is in bubble territory.
Speaking to Reuters today, Sago argued that the true fair value for bitcoin is around $100, adding that the current high value of the cryptocurrency is worse than the dot-com bubble of the late 1990s.
Sago said if bitcoin did drop to $100, the bank might consider buying it, but due to high volatility there are no plans to short-sell the cryptocurrency. According to the news source, the CIO also predicted that the bitcoin rally could top out around $10,000 when CME Group launches its bitcoin futures product – a move expected by the end of 2017.
However, he also aired a positive sentiment on blockchain technology and predicted that, in years to come, bitcoin could come to be widely used in settlement.
"The best thing to do here is to stay away from it [until then]," he said.
Sago's take on bitcoin mirrors views of other big names in finance. Earlier today, Morgan Stanley CEO James Gorman said bitcoin's meteoric price gains are "by definition speculative."

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
