Welcome to CoinRank Daily Data Report. In this column series, CoinRank will provide important daily cryptocurrency data news, allowing readers to quickly understand the latest developments in the cryptocurrency market.
Bitcoin reward mismatch with risk, similar to 2022
According to CoinDesk, CryptoQuant data shows that Bitcoin’s Sharpe ratio has gone deep into negative territory, reaching levels seen during the 2018-2019 and 2022 market crashes, indicating that its risk-adjusted performance is poor and that the current high volatility does not match weak returns.
This metric measures excess return relative to the risk-free rate versus volatility. Its turning negative means that the returns from holding Bitcoin no longer compensate for the risk of wild price swings.
Although the price of Bitcoin has dropped from its historical high of over $120,000 in October 2025 to around $90,000, market volatility remains high.
Historical data shows that negative Sharpe ratios can persist for months after prices have stopped falling significantly, such as during the lengthy bear markets of late 2018 and 2022.
Analysts pointed out that the ratio is not an accurate bottom signal, but it shows that the risk reward has been reset to the level before the launch of major market movements in history.
The focus is usually on whether the ratio can sustainably move back into positive territory, which usually means returns are starting to outweigh volatility, more consistent with the start of a new bull market. There are currently no signs of such a turnaround.
India strictly bans trading of privacy coins and requires crypto platforms to remove anonymous tokens
According to The Economic Times, the Financial Intelligence Unit under the Indian Ministry of Finance has asked domestic cryptocurrency exchanges and platforms to stop providing Anonymity Enhanced Crypto Tokens (ACE), not allow deposits or withdrawals of related tokens, and regard them as “unacceptable assets” under the risk mitigation framework.
The FIU also warned that mixing coins through tools such as “tumbler” and “mixer” and transferring funds to self-hosted wallets may cause funds from sanctioned or blacklisted addresses to flow into the system and become difficult to trace.
Platforms need to collect data related to non-custodial wallets and evaluate whether to set a limit on such transfers.
The Bank of Japan kept interest rates unchanged at 0.75%, in line with market expectations
The Bank of Japan kept its benchmark interest rate unchanged at 0.75%, in line with market expectations.
The interest rate decision was passed with a vote of 8-1. Bank of Japan review member Moto Takada held a dissenting opinion.
Takada believes that the price stability goal has been basically achieved, and given that overseas economies are in the recovery stage, the risks facing Japanese prices are biased towards the upward trend.
It is proposed to raise the short-term interest rate target from 0.75% to 1.0%.
The Bank of Japan stated that the median core CPI expectations for the fiscal year 2025-2027 are 2.7%, 1.9%, and 2.0% respectively. (October expectations were 2.7%, 1.8% and 2.0%).
The median real GDP growth forecasts for fiscal year 2025-2027 are 0.9%, 1.0%, and 0.8% respectively (the forecasts in October last year were 0.7%, 0.7%, and 1.0%).
If the economy and price trends are consistent with its forecast, and as the economy and prices improve, the policy interest rate will continue to be raised.
