A month ago, here I described how to create such a cold wallet, which will be perfect for hodling :)
I've also linked there another article of mine, which describes, how to set a password for your steem account, which is not generated by Steemit website :)
Also, I am right now in the middle of my power-down process to transfer all my SteemPower from @noisy, to @noisy.cold, and to be honest... I feel much more secure since I started :) Of course, I delegate all that SP from @noisy.cold to @noisy, so... actually, nothing changed for in terms of my voting power :)
