Which is Best Protection Software Add License/Key System

[giv]

In any case the software will be cracked. ALWAYS.
Just take the last Themida case.
All his virtual machines have been deobfuscated (last Eagle VM too).

The same will be with VMProtect and others too.
In .NET framework case also.
A dedicated person will always defeat any protection.
The problem is if it will put on the web the deprotecting tool or it will keep private.
So the focus can be on a good product not on the product protection.
