Sir! Trezor is not a cryptocurrency. but you can consider it your "safety deposit box any where you go". though, i am not sure how this thing works as it is quite complex for me as i am used to send / receive from my wallet without signing. But i am very open to this Trezor thing.

just have some few curious/newbie questions.
1. what if i forget my passkey?
2. do i rely on other peoples database for the storage of my bitcoin?
3. can this be used for LTC?

forgive me for popping these noob q's, I know, I know, google is my friend. but i was hoping this thread can explain further (laymans/gals term) for the benefit of us newbs 

Thankkk you. Mabuhay!
