This information is suggesting that the European Union’s financial regulator has raised concerns about a significant concentration of cryptocurrency trades and transactions happening through a limited number of exchanges. This could potentially mean a high risk of market manipulation, fraud, and security breaches as these favored exchanges become more attractive targets for malicious activities. It could also lead to liquidity issues if these exchanges were to abruptly halt their operations for any reason. The regulator likely urges for more diversity and decentralization within the market to reduce the associated risks.
