instead of buying hardware wallet that cost double/tripple the cheapest android phone in the market, can one simply dedicate an android phone that normally put offline to store private keys?

instead of buying expensive hardware wallet like Trezor that cost double/triple the cheapest android phone in the market, can one simply dedicate an android phone that normally put offline to store private keys?

another question: if you lost Trezor, how do you get a backup if no one else has another copy of it?

out of topic, but your avatar looks a bit like what i have learn from the biology class.

i think there is a dilemma here:

1. for trading you need to put coin on exchange

2. for safety you need to put coin in own wallet.

so i guess you cant have both safety with ease of trading same time?
