stake your coins on a Raspberry Pi. i think it's more safer
now the noobs question, how it works because , i never staked coins before, i just started it now , is just download install and put the coins there and its done?
take 1 Raspberry Pi 2, install a wallet
and let it run 24/7
Raspberry Pi 2 because he is efficient (max. 4 Watts)
which coin do you want to stake?
