About the size of a USB flash drive, Ledger devices connect to your phone or computer to store and access your digital holdings. The device is surrounded by a stainless steel cover, which makes it very durable.
With included Ledger Live software, you can check your balance, and send and receive currencies.
The basic Ledger Nano S and Bluetooth-enabled Ledger Nano X cost $59 or $119, respectively. Nano S supports up to 27 currencies and has capacity for up to six applications at a time, while Nano X holds up to 100 applications at a time.
Apps may be needed for certain currencies and other purposes, which means you may not be able to use all supported currencies at the same time with one device. Both use highly secure chips similar to the ones used in a chip-based credit card or passport.
