Private bitcoin transactions in Samourai Wallet achieve an ATH
The ATH balance available for private transactions is 4,755 BTC. The volume of private bitcoin transactions in Samourai Wallet is 750 BTC in 30 days, achieving an ATH.
In an age when privacy is scarce, it is not uncommon for individuals to be concerned about it daily. A proof of this is the use of tools focused on obtaining it. Among them are wallets that mix bitcoin transactions. One of these reached a record today, surpassing 4,755 bitcoin (BTC) of unspent capacity or available balance.
According to a release from one of the developers leading Samourai Wallet, the available BTC balance for those using this type of private transaction contrasts with its volume over the past 30 days, which has been 750.26 BTC. This tool, called Whirlpool, is designed to make private transactions in Bitcoin, a network that has a public ledger.
In June 2021, the amount of available bitcoin balance among users using Whirpool to mix cryptocurrencies was 3,000 BTC, according to Samourai Wallet figures. It was an increase of 37% in one year.
When we talk about mixing bitcoin transactions, we refer to a method known as CoinJoin. A tool such as Samourai Wallet‘s Whirlpool allows to make payments or receive balances without the origin or destination of each transaction known.
For this type of operation to occur, users have to agree with each other. So that they can use their unspent balance (UTXO) in a single process that pools or mixes the joint transactions of several people. In principle, the more people participate in the pool, the higher the level of privacy.
Other private Bitcoin wallets than Samourai Wallet provide financial anonymity.

Samourai Wallet is not the only wallet using Whirlpool. Sparrow, a relatively young desktop wallet, also uses the tool. It implies that the number of people using some method to conduct private bitcoin transactions continues to grow.
Another wallet known for its approach to privacy announced that it would begin censoring addresses that use CoinJoin. That corporation began working with an analytics firm that the community has identified as a significant participant that violates the privacy of Bitcoin users.
According to the company that developed Wasabi, the decision obeys a requirement of the Financial Action Task Force (FATF), which in October last year issued a series of recommendations to prevent money laundering and terrorist financing.
In any case, Wasabi, which may have lost many of its users, as a result, is not the only wallet for safer transactions.
The amount of balance available on Whirlpool for private BTC transactions has already surpassed the balance on other networks that offer a certain level of privacy. It is the case of Bitcoin’s Lightning Network, which has a capacity of 3,880 BTC between its payment channels, and it represents 900 BTC less than Samourai Wallet’s Whirlpool capacity.
A Samourai Wallet tweet reads a sentence that could be a slogan with the best bitcoiner essence:
“Financial privacy is not just a popular thing; it is a prerequisite for a free society.”

Bitmine Buys Over 100K ETH, Moves Closer to Controlling 5% of Supply
Bitmine Immersion Technologies has made another massive Ethereum purchase, reinforcing its position as the largest public holder of Ether and pushing closer to its ambitious long-term accumulation target.
Bitmine’s Biggest ETH Buy in Months
The company acquired 101,627 Ether (ETH) during the week of April 13 to April 19, marking its largest purchase since December 2025.
This latest buy continues a streak of aggressive accumulation over the past month, signaling strong conviction despite recent market volatility.
Total Holdings Near 5 Million ETH
Following the purchase, Bitmine now holds:
- 4,976,485 ETH
- Valued at დაახლოებით $11.5 billion
- Roughly 4.12% of total Ethereum supply
The company also maintains additional assets, including:
- 199 Bitcoin (BTC)
- Over $1.1 billion in cash
- Strategic equity stakes in multiple firms
Altogether, Bitmine’s crypto and cash holdings total around $12.9 billion.
Chasing the “5% Supply” Target
Bitmine has made it clear that its goal is to control 5% of Ether’s circulating supply, a strategy it calls the “alchemy of 5%.”
With current holdings, the company is now about 82% of the way to that target.
If achieved, it would represent one of the most concentrated institutional positions in a major cryptocurrency.
Expanding Ethereum Staking Operations
Beyond accumulation, Bitmine is also scaling its staking infrastructure through its MAVAN platform.
- 3.33 million ETH is currently staked
- Generating over $200 million annually in staking rewards
This allows the company to earn yield while holding a large treasury position.
Strategy Reflects Long-Term Bullish Outlook
Chairman Tom Lee said the company believes Ethereum is emerging from a “mini crypto winter,” suggesting the recent downturn may be nearing its end.
Bitmine’s continued buying indicates confidence in:
- Ethereum’s long-term growth
- Institutional adoption trends
- The role of staking in generating sustainable returns
Institutional ETH Accumulation Is Growing
Bitmine’s strategy reflects a broader shift, where public companies are increasingly building crypto treasuries similar to Bitcoin-focused firms.
Ethereum, with its staking yield and smart contract ecosystem, is becoming a key asset in these strategies.

Japan to Test Government Bonds as Digital Collateral on Canton Network
Japan is taking another step toward modernizing its financial infrastructure, with a new pilot exploring how government bonds can function as digital collateral on blockchain rails.
Major Institutions Join Digital Collateral Trial
The Japan Securities Clearing Corporation (JSCC), part of the Japan Exchange Group, is leading the initiative alongside:
- Mizuho Financial Group
- Nomura Holdings
- Digital Asset
Together, they will test whether Japanese government bonds can be digitized and used efficiently within blockchain-based financial systems.
Bringing Government Bonds Onchain
The pilot focuses on using Japanese Government Bonds (JGBs) as digital collateral on the Canton Network.
Key objectives include:
- Enabling onchain transfer and management of bonds
- Preserving their legal status under existing regulations
- Testing integration with current financial infrastructure
The goal is to determine whether traditional assets can move seamlessly into blockchain environments without disrupting legal frameworks.
Toward Real-Time, 24/7 Collateral Markets
One of the most important aspects of the trial is exploring real-time collateral usage.
Unlike traditional systems that operate within limited hours, blockchain infrastructure could enable:
- 24/7 collateral transfers
- Faster settlement times
- Cross-border efficiency
This could significantly improve how financial institutions manage liquidity and risk.
Backed by Japan’s Financial Regulator
The initiative has been selected by the Financial Services Agency under its Payment Innovation Project.
This signals strong regulatory support for experimenting with distributed ledger technology in core financial markets.
Building on Global Momentum
Japan’s move follows similar experiments in other markets.
A previous Canton Network pilot tested tokenized US Treasuries as reusable collateral among major global banks, demonstrating how high-quality assets can circulate more efficiently onchain.
The new trial extends that concept to one of the world’s largest sovereign bond markets.
Implications for Financial Infrastructure
If successful, the project could:
- Redefine how collateral is managed globally
- Improve capital efficiency for institutions
- Accelerate the adoption of blockchain in traditional finance
However, no timeline for a full commercial rollout has been announced yet.
A Step Toward Tokenized Finance
This initiative highlights a broader trend of integrating traditional financial assets into blockchain systems.
By testing government bonds as digital collateral, Japan is positioning itself at the forefront of the shift toward tokenized financial infrastructure.
