Cryptocurrency compliance firm Bitrace found that $649 billion worth of stablecoins flowed through addresses classified as high-risk in 2024, according to an April 29 report.

Bitrace defines high-risk blockchain addresses as those used by illegal entities to receive, transfer or store stablecoins.

Crypto compliance firms typically score crypto wallet addresses based on their likelihood of involvement in illicit activities. The higher the risk, the higher the likelihood of foul play, and the less likely compliant crypto businesses are to accept the assets.

Per the report, the amount accounted for roughly 5.14% of all stablecoin transaction volume in 2024. This is down 0.8% from 5.94% the previous year, but significantly higher than the 2.8% reported in 2022 and 1.63% in 2021.

Tron USDT tops high-risk transactions

Tron-based USDt (USDT) dominates high-risk stablecoin transactions, with Bitrace data indicating that well over 70% of the volume moved on the network. The remaining high-risk stablecoin transactions are mostly Ethereum-based USDt and a small amount of USDC (USDC).

A likely explanation for the prevalence of USDT is likely due to its larger market capitalization and adoption compared with other stablecoins. At the time of writing, CoinMarketCap shows that USDt has a market cap of over $148 billion, while USDC stands at over $62 billion.

Tron’s prevalence is not as easy to explain. Ethereum remains the more popular choice for most stablecoin users, with DefiLlama showing nearly $124.3 billion worth of stablecoins circulating on the network. Tron ranks second, with about $71 billion — almost 43% less than Ethereum.

When comparing USDT balances alone, Tron holds slightly more than Ethereum: 47.4% of USDT supply, versus Ethereum’s 45.44%.

Crypto gambling continues its rise

Bitrace also reported that in 2024, online gambling platforms processed $217.8 billion worth of stablecoins — a 17.5% increase over the previous year.

Once again, USDT also dominated this type of activity. Still, USDC’s market share is rapidly rising, clocking in at 13.36% in 2024.

The data follows recent reports that crypto casinos generated more than $81 billion in revenue in 2024, even as regulators in key jurisdictions continued to block access to the platforms, according to a new report.
