Stablecoins are going mainstream — could Bitcoin, Ethereum, and crypto stocks be the real winners?

Stablecoins are becoming one of the fastest-growing parts of the crypto market, but the biggest trading opportunities may sit elsewhere. Circulation of USDC—the dollar-backed stablecoin issued by US-listed digital-finance company Circle—reached $73.3 billion last quarter, up 19% from last year, while on-chain transaction volume surged 151% to $14.8 trillion. Circle is now preparing to expand into around 40 additional markets as demand grows across Asia, Latin America, Africa and the Middle East.

At the same time, major payment networks and banks are starting to use stablecoins for settlement rather than treating them purely as crypto-market instruments. Visa’s stablecoin settlement activity has scaled rapidly, while Standard Chartered now allows institutional clients to mint and redeem USDC through its banking infrastructure.

For traders, the opportunity is not necessarily USDC itself. The stablecoin is designed to remain close to $1, leaving little reason to speculate on large price moves.

The more interesting question is what happens around it. Stablecoins can make it easier for capital to move between traditional finance and crypto markets, increase blockchain activity, and give institutions a more practical way to hold and transfer digital dollars. That could create opportunities across Bitcoin, Ethereum, and crypto-linked stocks if adoption continues accelerating.

Stablecoins have traditionally played a simple role inside crypto markets: they give traders a dollar-like asset that can remain on-chain without constantly converting back into a bank account.

That role is becoming much larger. Transaction volumes have skyrocketed, while Circle now has more than 100 institutional and ecosystem participants building on its Arc blockchain infrastructure. Visa has also expanded stablecoin settlement across nine blockchains, showing that the technology is moving beyond crypto exchanges and into mainstream payment networks.

That expansion can create a larger pool of capital already sitting inside digital-asset infrastructure and ready to move between stablecoins, Bitcoin, Ethereum and other crypto markets.

For traders, the significance is liquidity rather than stablecoin price appreciation. More stablecoins circulating across exchanges, payment platforms and institutions can make it easier for capital to move quickly when sentiment changes.

For Australian traders, those developments are more relevant when viewed through markets that can actually move. Bitcoin, Ethereum and other crypto CFDs can react to shifts in liquidity, institutional participation and blockchain activity even when the stablecoin itself remains anchored near $1.

Bitcoin does not directly depend on stablecoins, but the two markets are increasingly connected through liquidity. Investors who want to reduce crypto exposure do not always need to leave the digital-asset ecosystem completely. They can move into stablecoins and remain ready to re-enter Bitcoin when conditions improve.

That creates a pool of capital that can move faster than money entering from traditional bank accounts. If sentiment turns bullish, stablecoin balances can be converted into Bitcoin quickly; if risk appetite weakens, the same money can remain parked in digital dollars.

Growing institutional adoption could increase that effect. Standard Chartered’s integration with USDC allows eligible institutional clients to move between fiat banking and digital assets without needing a separate direct account with Circle.

Bitcoin would still respond primarily to larger forces such as interest rates, ETF flows, and investor risk appetite, but expanding stablecoin liquidity could make capital movement into crypto markets faster and more efficient.

For CFD traders, that means stablecoin circulation and transaction volumes could become another useful indicator alongside ETF flows, yields, and broader market sentiment.

Ethereum potentially has a stronger connection because stablecoins generate activity on blockchain networks themselves. When USDC or other stablecoins move between wallets, exchanges and institutions, those transactions require blockchain infrastructure. Greater settlement activity can therefore increase network usage across Ethereum and competing chains.

That does not guarantee higher ETH prices, but it can strengthen the fundamental case for networks that process a large share of stablecoin transactions.

The opportunity becomes more interesting as stablecoins move into areas such as cross-border settlement, tokenised assets and automated payments. Visa already supports stablecoin settlement across multiple blockchain networks, while Circle is positioning Arc as infrastructure for programmable finance and tokenised real-world assets.

Ethereum therefore offers a different exposure from Bitcoin. Bitcoin benefits mainly from greater crypto liquidity and institutional participation, while Ethereum can also benefit from rising activity across the digital financial infrastructure itself.

For traders, ETH transaction volumes, network activity and the share of stablecoins operating across Ethereum and rival networks can help show where that growth is being captured.

The stablecoin opportunity is also moving beyond crypto assets. Visa’s stablecoin settlement pilot reached a $7 billion annualised run rate earlier in 2026 and has since expanded across additional blockchains. The company also had more than 160 stablecoin-linked card programs live or in development, with payment volume growing rapidly.

The commercial appeal is straightforward. Stablecoins can allow banks, fintechs and payment providers to settle transactions seven days a week instead of waiting for traditional banking windows, while also making cross-border transfers faster and potentially cheaper.

That turns stablecoins into a financial-infrastructure theme rather than simply another crypto narrative.

For stock traders, companies that provide the rails connecting digital dollars to traditional payments may benefit without taking direct cryptocurrency price risk. Circle has direct exposure through USDC circulation and reserve income, while Visa is embedding stablecoin settlement into its existing network.

Banks are also becoming involved. Standard Chartered’s institutional USDC service gives traditional financial clients a regulated route into stablecoin settlement, suggesting larger financial institutions increasingly see digital dollars as infrastructure rather than a speculative product.

Stablecoin growth can improve liquidity without producing an immediate rally in Bitcoin or Ethereum.

The same stablecoins that allow investors to enter crypto markets quickly also allow them to move out of volatile assets without leaving the blockchain ecosystem.

If USDC circulation rises while Bitcoin and Ethereum remain weak, that could indicate investors are holding more capital in digital cash rather than deploying it into riskier crypto assets.

The more bullish setup would combine rising stablecoin circulation with stronger Bitcoin and Ethereum volumes, increasing ETF demand and improving broader risk appetite. That would suggest new liquidity is being deployed rather than simply parked.

This distinction is useful for traders because stablecoin growth can signal increasing capacity for crypto activity without telling them which direction prices will move.

The opportunity comes when liquidity growth is accompanied by changes in positioning and price momentum.

Greater liquidity usually improves market depth, but faster capital movement can also accelerate price moves. Stablecoins operate continuously, allowing money to shift between crypto assets at weekends and outside traditional market hours. As banks and payment networks make stablecoin settlement easier, institutional capital could become more responsive to changes in market conditions.

A sharp change in interest-rate expectations, regulation or crypto sentiment could therefore trigger quicker movements between stablecoins and volatile assets.

For CFD traders, that creates opportunities on both sides of the market. Crypto CFDs allow traders to take long positions when expecting Bitcoin, Ethereum, or other digital assets to rise and short positions when expecting them to fall.

USDC circulation provides one of the simplest measures of how much dollar-denominated liquidity is sitting inside the digital-asset ecosystem. Continued growth from the current $73.3 billion would support the case that stablecoin adoption is still expanding.

Transaction volume can provide another signal. USDC’s 151% year-on-year increase in second-quarter activity shows adoption is growing much faster than circulation itself, suggesting each dollar of stablecoin supply is being used more frequently.

Institutional integrations are also worth following. More banks, payment networks, or asset managers adopting stablecoin settlement would strengthen the connection between traditional finance and blockchain markets.

For Bitcoin and Ethereum traders, the most important signal would be whether rising stablecoin activity starts coinciding with stronger crypto trading volumes and price momentum. That would provide clearer evidence that additional liquidity is flowing into volatile assets rather than remaining in digital dollars.

Trading the stablecoin trend with Mitrade

Stablecoins themselves are designed to avoid large price movements, but their growth can still create opportunities across the wider crypto market.

Through Mitrade, eligible Australian clients can trade CFDs on Bitcoin, Ethereum and a range of other cryptocurrencies without buying or storing the underlying digital assets. 

That means traders can use stablecoin circulation, institutional adoption and blockchain activity as part of a broader market view without needing to own USDC directly.
