It should be pretty safe and the chances of purchasing a fake device are decently low. You just need to make sure that you reset the device yourself and generate your own wallet (with your own 24-word backup phrase).
Should you buy a used Ledger hardware wallet?
We heavily recommend against purchasing used or second-hand hardware wallets.
While the chances of something bad happening is low, is it really worth it? One of the main reasons for purchasing a hardware wallet is to secure your bitcoin and cryptocurrencies. Purchasing a second-hand Ledger hardware wallet unnecessarily increases the risks, in exchange for only a small amount of money.
One thing’s for sure, security is one of those things that no one should cheap out on.
Where should you purchase a hardware wallet?
Always purchase the hardware wallets on their official websites. In this case: Ledger.com
Just like purchasing second-hand hardware wallets, you’re increasing your risks when purchasing hardware wallets from 3rd party websites like Amazon, Lazada, eBay, Shopee, and others.
Depending on where you’re from, while purchasing from Ledger directly may cost you a few more dollars, it’s worth paying that small premium for the extra security.
Trust me, it will make you sleep better knowing that what you own is 100% legitimate!
