Steam Wallet Hack?

Hello!

So I have noticed that are many steam wallet hack out there, specilly on YouTube. So I woundering if there is anyway to really hack the steam wallet system and get real money on your account? Or are all this hacks just fake and just trying to troll people to make annoyings ******?
But there are also some hacks that don't have ******s, but these hacks does not working because there are outanded or running with some random program like .NET or C++

But are there any hack which working?

All the money you "earn" from the "hack" was mean to be spend on TF2 :C

Hacking Steam wallet balance is pretty much equal to hacking Paypal's balance or your Bank account balance.
It is actually weird to me that somebody might think that those programs on youtube are not viruses, it's quite obvious.
