How many coins can be stored on Ledger hardware wallets?
Ledger hardware wallets (Ledger Nano S or Ledger Nano X) support over 100 different cryptocurrencies. Among them are all the well-known coins like Bitcoin, Ethereum or Ripple. A complete overview can be found here:Ledger supported cryptocurrencies.
In principle, as many supported coins/cryptocurrencies can be stored on the Ledger Nano S as you like. The hardware wallet only stores the private keys that ensure access to the coins. To manage the coins, the corresponding app must be installed on the device.
However, you can only install a certain number of apps at a time on the Ledger Nano S or Nano X. This is because the memory of the Ledger Nano S and Nano X is limited. However, it is not a problem to switch apps by un- and install, so the coins are not lost.
