Although a hardware wallet is the safest and most secure way to store your altcoins.

But there is a downside of hardware wallet if you lose access to your Recovery phrase, password, and security pin then there is no way you can recover your security information.

So it essentially means you have lost your Bitcoins as someone has stolen them from you.

It is important to make two to three copies of all important codes and passphrases and save them two to three different locations from where you can access them in case of mishappening.

Using some prudence and a bit of common sense can help you to enjoy the world of cryptocurrency while being safe and secure the entire time.

Final verdict ( Trezor One vs Ledger Nano S vs Keepkey)

Each hardware wallet listed above is of the highest quality with minor differences.

But they all have one thing in common i.e. they are extremely secure and have been trusted by the cryptocurrency community.

For me, Ledger nano S marginally tops the list, Trezor comes second, and Keepkey third. Ledger supports all major cryptocurrencies and they are consistently adding new features to their arsenal. It is one of the cheapest hardware wallets with enough security features.

Although, Trezor is the most reputable hardware wallet in the comparison of Trezor vs Ledger vs Keepkey. But its fragile plastic body makes it more susceptible to damage.

Overall Trezor is also one of the best hardware wallets and you won’t regret your decision to buy it ( But handle it with care)

Keepkey doesn’t justify its high price and its larger size makes it quite inconvenient to carry. Trezor Model T is quite expensive to my liking.

I am still using Ledger Nano S and Trezor One and they both serve their purpose well.

So if you are thinking to involve in cryptocurrency games for the long term then you should buy at least one of the above best hardware wallets.

For me the comparison of Trezor One vs Ledger Nano S vs Keepkey wallet stand out in the order:

Ledger Nano S > Trezor One > Keepkey
