There's a recent update for Ledger live and that's what the title says, you can now purchase crypto using their app as they've integrated with Coinify. The available cryptos are not that much yet this may be ease for other users.
This feature, operated by Coinify, is available directly in the Ledger Live application. Pick your favorite crypto among Bitcoin, Ethereum, Bitcoin Cash, or Dash and buy it using your Credit Card or a Bank Transfer. Stellar and USDT will soon be available to buy directly through Ledger Live.
