In feedback submitted March 20 on the European Commission's proposed Market Integration Package, the company backed expanding the DLT Pilot Regime but asked for adaptive thresholds and clearer routes from pilot programs to permanent rules.

Bernstein said Circle (CRCL) and Coinbase (COIN) remain the most direct ways to gain exposure to stablecoin growth, pointing to their shared USDC ecosystem.
