Bitcoin + stablecoins now dominate 73.5% of market cap – a known precursor to altcoin rallies.
Something interesting’s cooking, and it’s very easy to overlook if you’re looking only at Bitcoin [BTC].
Stablecoin supply has surged past $250 billion, and with BTC holding an outsized share of that capital, one does wonder: when does the money rotate?
While skepticism still lingers, familiar patterns are beginning to emerge; the same ones that have been recognized as the early stages of major altcoin breakouts.
Locked and loaded
The 90-day change in aggregate stablecoin supply has flipped green, similar to levels last seen before major market rallies.
Weekly inflows now account for billions, so this isn’t idle capital parked on the sidelines.

It’s more like dry powder—capital waiting to be deployed when risk appetite returns.
As stablecoin reserves grow, the market appears to be entering a re-accumulation phase, with ample liquidity ready to fuel the next altcoin breakout once macro conditions and momentum align.
Tether holds the lion’s share
As the total stablecoin market cap inches toward $250 billion – roughly 7.5% of crypto’s total valuation – one player continues to tower above the rest.

Tether [USDT] now accounts for a commanding 66.2% of all stablecoins in circulation. This dominance shows deep liquidity and trader trust, positioning Tether as the primary bridge between fiat and crypto.
USDT dominates capital flows, centralizes liquidity, and signals when and where stablecoin reserves will move next.
However, there’s rising concern that this concentration of liquidity may not translate into direct support for decentralized markets, as some had anticipated.
Sebastian Pfeiffer, Managing Director of Impossible Cloud Network, told AMBCrypto,
“Many are celebrating the liquidity this stablecoin boom will supposedly bring to digital assets, but few seem to be clear where that liquidity will go…”
He further added,
“Because it seems unlikely all of this stablecoin liquidity will find its way into the decentralized crypto ecosystem. Indeed, it seems far more likely it will stay in the hands of the centralized providers and systems controlling these assets.”
So, how much of this boom translates to altcoin upside?
Can any of this lead to altseason?
Bitcoin and stablecoins now make up 73.5% of the total crypto market cap—a level last seen during major altcoin accumulation phases in previous cycles.
Historically, when BTC and stablecoin dominance surges above 70%, it signals that investors are parking capital in lower-volatility assets, often a precursor to rotating into riskier altcoins once market conditions turn favorable.

Despite skepticism about an incoming altseason, current data tells a different story. \
A large amount of sidelined capital is parked in Bitcoin and stablecoins, waiting for the right technical setup or narrative spark to flow back into higher-risk altcoins.
