These hardware wallets which are very popular among the community today; Trezor and Ledger more specifically are seen as gods gift among the community and everyone believes they are 100% safe. But, can we really trust those behind the development?
That is why I decided to replace my Ledger Nano S with the latest Trezor T. Trezor software is open-source so everyone can check if the code is bug-free or if there are any backdoors. Ledger devices are based on secure elements which have limited space and capabilities and most importantly, we can't see what happens inside it. Also, Ledger has started working with Intel which is known for problems with Intel Management Engine. I don't trust developers, I trust community that checks the code provided by them.
