Air traffic control is often pegged as the most stressful job in the world. 

Managing private key security at Coinbase might just take the cake. 

Coinbase is big. Influential. On the front lines of the war for hearts, minds and regulatory clarity.

There’s no greater way to prove Coinbase’s standing in the crypto space than by just how much of it is given to it for safekeeping.

We know now that Coinbase users held $272.7 billion in crypto at the end of September, plus an additional $4 billion in cash. 

That’s nearly $3.5 billion more crypto than at the end of June — probably in part boosted by rising asset prices — and $200 million less cash than the prior period.

Then, there’s all the crypto tied up in Grayscale’s suite of ETPs and ETFs: $22.62 billion at Q3’s close, per Arkham Intelligence data. Grayscale went all-in on Coinbase Custody back in 2019. 

Another $31.7 billion is custodied on behalf of other ETF issuers like BlackRock, Bitwise and Ark/21Shares. 

Three nickels of every dollar of crypto value on the planet is kept with Coinbase

Coinbase’s final total for Q3: $331 billion, the equivalent of 15% of the total crypto market cap at the time.

And if you want to go even deeper: Chainalysis recently estimated that about 1.8 million BTC could be lost forever — or 9.1% of the circulating supply. 

Scrub that from crypto’s market cap, along with the 1.1 million lost Satoshi coins, and Coinbase would technically be sitting on closer to 17% of crypto’s remaining paper value.

No doubt, Coinbase recognizes the significance of it all. Still, the way things are going, Coinbase could go down as one of the most aptly named companies in fintech history: 

A base for literally all the coins.

Kinetiq has established itself as Hyperliquid's dominant liquid staking protocol, holding 82.5% of LST market share with $610M in TVL. The protocol is now expanding beyond its kHYPE staking core into higher take-rate verticals: iHYPE for institutional custody rails, Launch for HIP-3 capital formation, and Markets for builder-deployed perpetuals. We view Markets, launching Jan. 12, as the highest-potential product line given its mechanically scalable, activity-linked unit economics. Near-term revenue remains anchored by kHYPE's KIP-2 fee schedule (~$1.6M annualized), while Markets provides embedded optionality if HIP-3 economics normalize post-Growth Mode. KNTQ's setup is relatively clean: zero insider unlocks until November 2026, 6.2% buyback yield from staking revenue, and cleared airdrop overhang. Risks center on unproven Markets execution, declining kHYPE TVL despite ongoing incentives, and competition from Hyperliquid's native initiatives.
