On Christmas,I received a letter, looking at the sender, I found nothing, except an 'anonymous'. I didn't understand why, but as I kept reading, it finally dawned to me that this is a puzzle, and here it is.
What ye may think of this, a puzzle! What ye need to figure out, a passcode. >Axcjcn kh 9 mrprcb.. Vh oacnwm.

I will give you a few sentence, and that's all you'Il need to figure out what you have to do to get the gift.. ;) good luck! "I'm something useful, untouchable, yet buyable. I am expensive, however l'm not sensitive, I feel nothing. I'm the 2nd generation, without DNA. What l'm worth? I go up and down. I'm short with 3 letters. But guess what? I'm useful! I power many of my kinds, my cost is at 4 digits, and without me, most of my kinds wouldn't even exist. I guess l'm pretty important then..." That's it! Figure what I am talking about...send me back a letter, and l'll give you one of it!
Best of luck,
Of course I want the gift!, so help me!
