Shares of several popular altcoins, including Polygon (CRYPTO: MATIC), are trading lower in sympathy with apex cryptocurrency Bitcoin (CRYPTO: BTC) and second-largest market cap crypto Ethereum (CRYPTO: ETH).
Crypto is likely trading lower in tandem with major U.S. indices. Major indices are lower following worse-than-expected May CPI data. Rising inflation has caused economic concerns and has also raised expectations for further Fed policy tightening.
