Coinbase today delisted a number of big cryptocurrencies—including Ripple’s XRP, the seventh largest digital asset by market cap—from its wallet app. 

In a Tuesday announcement, America’s biggest exchange said that from January 23 it would no longer support Bitcoin Cash (BCH), Ethereum Classic (ETC), Ripple (XRP), or Stellar (XLM) on Coinbase Wallet. 

Coinbase said the move was “due to low usage” of the assets on the platform. Coinbase Wallet is a self-custody mobile app, similar to other software wallets such as MetaMask, though with a wider array of support for crypto assets.
