The cryptocurrency market has recently witnessed a striking accumulation of Bitcoin by a mysterious wallet address dubbed “Mr.100.” Since February 15, this entity has been systematically purchasing over 100 BTC per transaction on nearly a daily basis. As Bitcoin surged past the $60,000 mark, the buying pace accelerated — sparking speculation among analysts that this may not be an individual investor, but rather institutional or market-making activity.
This surge in whale accumulation highlights growing confidence in Bitcoin’s long-term trajectory and suggests strategic positioning ahead of potential macroeconomic shifts. With over 7,700 BTC acquired in just one month, the activity has drawn attention from chain analysts and traders alike.

The Rise of Mr.100: A Pattern of Strategic Accumulation
According to data from BitInfoCharts, the wallet known as Mr.100 executed 15 separate transactions on February 28 alone, amassing a total of 1,622 BTC in a single day. The following day, it repeated the pattern — conducting 16 transactions and acquiring 1,611 BTC, with some purchases made at prices as high as $62,990 per BTC.
On March 1, the activity continued with two large buys totaling 208.87 BTC, maintaining the consistent strategy of incremental accumulation. This disciplined approach — avoiding large, market-moving transactions — suggests a sophisticated actor aiming to minimize slippage and avoid drawing premature attention.
"The behavior is too consistent for a retail investor. This looks like algorithmic buying, possibly orchestrated by a market maker or exchange-affiliated entity," said a blockchain analyst tracking the address.
As of the latest data, Mr.100 holds a total of 51,064.18 BTC, valued at approximately $3.14 billion** at current prices. The unrealized profit on this position stands at an estimated **$1.6 billion, indicating that much of the acquisition occurred at significantly lower price levels.
Ranking Among the Top Bitcoin Whales
With this volume of holdings, Mr.100 now ranks as the 15th-largest Bitcoin wallet globally. Its stash represents 0.2595% of Bitcoin’s total supply — a non-trivial share in a decentralized ecosystem where distribution is closely watched.
What makes this accumulation particularly notable is its timing and consistency. Over the past 30 days, Mr.100 added 7,723 BTC to its balance — all while maintaining a low profile through fragmented transactions across multiple platforms.
Key Bitcoin Whale Metrics:
- Total Holdings: 51,064.18 BTC
- Current Value: ~$3.14 billion
- Unrealized Profit: ~$1.6 billion
- Monthly Accumulation: 7,723 BTC
- Supply Share: 0.2595%
Such concentrated growth in holdings during a period of market optimism may signal confidence in upcoming bullish momentum — or preparation for increased liquidity provision.

Who Is Behind Mr.100? Clues Point to Asian Exchange Activity
Despite extensive analysis, the true identity of Mr.100 remains unconfirmed. However, on-chain researcher Mai has proposed a compelling theory: the wallet may be linked to Upbit, South Korea’s largest cryptocurrency exchange.
Mai’s assessment is based on several behavioral patterns:
- Geographic Activity Timing: Approximately 75% of transactions occur during Asian market hours, aligning with Upbit’s primary user base.
- Exchange Transaction Traces: Historical inbound transfers show origins from known Upbit and Bithumb deposit addresses.
- Trading Behavior: The use of multiple smaller wallets to aggregate BTC mirrors Upbit’s known strategy for acquiring altcoins on Ethereum.
Further supporting this hypothesis is the observation that 90% of purchases originate from Upbit and Bithumb, with only occasional trades on Binance and OKX. This exchange concentration strengthens the argument for institutional involvement rather than independent retail activity.
“This isn’t random speculation — the transaction signatures, timing, and funding sources all point toward an organized entity,” Mai noted on Twitter. “Given the patterns, it’s highly plausible this is a market-making or reserve-building operation tied to Upbit.”
Additionally, the use of automated scripts (bots) to execute small, frequent buys reflects institutional-grade infrastructure — further distancing the activity from typical individual investors.
Why Market Makers Might Be Accumulating Now
If Mr.100 is indeed a market maker or exchange-affiliated entity, its behavior makes strategic sense:
- Liquidity Preparation: As Bitcoin approaches key resistance levels and ETF inflows increase, exchanges need deeper reserves to handle higher trading volumes.
- Volatility Hedging: Accumulating BTC allows market makers to hedge against short-term price swings while profiting from bid-ask spreads.
- Arbitrage Opportunities: Holding substantial BTC positions enables cross-exchange arbitrage, especially between Korean and global markets where price premiums (the “Kimchi premium”) occasionally emerge.
- Staking and Yield Participation: With growing adoption of layer-2 solutions and yield-bearing protocols, holding large BTC balances opens doors to new revenue streams.
This kind of accumulation often precedes periods of heightened trading activity — suggesting broader market participation may soon follow.
Frequently Asked Questions (FAQ)
Q: What defines a Bitcoin whale?
A: A Bitcoin whale is an individual or entity holding a large amount of BTC — typically thousands of coins. These holders can influence market movements due to the size of their positions.
Q: Can we confirm Mr.100 is linked to Upbit?
A: Not definitively. While strong circumstantial evidence points to Upbit — including transaction timing and source addresses — there is no official confirmation. Blockchain analysis provides clues, not absolute proof.
Q: Does whale activity predict price direction?
A: Not always. While large accumulations often signal bullish sentiment, whales may also buy before distributing (selling) later. Context matters — including market conditions and transaction patterns.
Q: How does fragmented buying help large investors?
A: Breaking large purchases into smaller transactions reduces market impact, avoids price spikes, and maintains operational discretion — crucial for institutions managing billions in assets.
Q: Is this kind of accumulation legal?
A: Yes. As long as funds are obtained and traded compliantly, accumulating Bitcoin in this manner is fully legal and common among institutional players.

Final Thoughts: A Signal of Growing Institutional Confidence
The emergence of Mr.100 underscores a broader trend: increasing institutional engagement in Bitcoin markets. Whether this address belongs to Upbit or another major player, its methodical accumulation reflects a calculated belief in Bitcoin’s upward potential.
For retail investors, such whale movements serve as both a warning and an opportunity — a reminder to stay informed about on-chain activity and understand how large players shape price action.
As Bitcoin continues to mature as an asset class, monitoring these digital footprints will become increasingly vital for anyone serious about navigating the crypto landscape.
