Bitcoin Bet Climbs to 85% of Tom Lee's Portfolio

Tom Lee Says a 2% Bitcoin Allocation Grew Into 85% of Some Portfolios

Fundstrat Global Advisors founder and Bitmine Chairman Tom Lee says a small Bitcoin allocation recommended more than a decade ago dramatically reshaped the portfolios of clients who followed it.

According to Lee, Fundstrat advised clients who were willing to take on crypto exposure to allocate around 2% of their portfolios to Bitcoin and then leave the position largely untouched. Over time, he said, that modest slice grew to more than 85% of the average portfolio among those who followed the guidance—driven primarily by Bitcoin’s appreciation rather than continued buying.

The claim highlights a simple but important feature of long-run portfolio construction: when one asset experiences outsized gains, it can become a dominant driver of returns and risk, even if it started as a small allocation. In practice, that dynamic can leave investors far more concentrated than they initially intended, unless they periodically rebalance.

Lee’s comments come as large asset managers have increasingly discussed Bitcoin in traditional portfolio terms. In a revised 10-year analysis, BlackRock said a 1% to 2% Bitcoin allocation funded from equities would have improved risk-adjusted returns in a conventional 60/40 portfolio, while generally maintaining similar overall risk features.

BlackRock’s analysis also pointed to how positioning and leverage can influence crypto market behavior. The firm said speculative positioning became extreme when Bitcoin rallied above $120,000 in October last year, with futures open interest reaching as high as $90 billion and concentrated in leveraged perpetual futures on offshore venues. It added that macro-driven “risk-off” catalysts—such as tariff-related headlines—helped trigger deleveraging across precious metals and crypto, contributing to a liquidation cascade.

During that drawdown, BlackRock described Bitcoin as showing a “dual personality,” at times moving with risk assets as markets de-levered, while also acting as a potential hedge during geopolitical disruption, including around the US-Iran conflict. The firm said higher correlation with stocks has tended to be episodic rather than structural.

Lee has also argued that market positioning and prior market moves can reset conditions for future price action, citing an October 2025 flash-crash that coincided with Bitcoin’s most recent all-time high around $126,000. He has previously stated targets such as Bitcoin trading above $200,000 by the end of 2025, a level that did not materialize.

Separate industry developments underscore how crypto-related businesses are adapting as market conditions evolve. Bitcoin miner Core Scientific reported $164.2 million in revenue for the quarter ending in June, with $136.7 million coming from its colocation data center business and $21.5 million from self-mining. The shift illustrates how some mining operators are leaning more heavily on steady infrastructure revenue—such as renting capacity to AI companies—rather than relying primarily on block rewards.

What happened: Lee said a 2% Bitcoin allocation recommended over a decade ago grew into more than 85% of some portfolios due to appreciation.
Why it matters: Even small crypto allocations can become major sources of both returns and concentration risk over time.
Broader context: Firms like BlackRock have framed Bitcoin as a potential portfolio diversifier at low weights, while also emphasizing leverage-driven volatility and shifting correlations.
