The two largest companies, ledger and trezor, are the most important manufacturers of hardware wallets. To compare ledger nano s wallet, I want to compare the manufacturer with trezor, which considering that trezor has been working in this field for a long time and ledger entered the industry in 2014, but there are two main competitors and I I know people who strongly accept the security of ledger wallets.
Working with ledger nano s is very simple and it looks like a flash memory and I consider this an advantage that reduces the possibility of stealing its physical object (because thieves may not recognize that this is not a flash memory)
The security of ledger nano s is so high that although many people keep their currencies in it, the security holes are almost unreported.
