Is there any hope for such a binding on a PC?

Question

C++ / C#

I am writing an application for which a monthly payment will be required, so a hardware binding was required.
The application has access to the WEB server (to the database)
I found this method on the Internet, where there is a binding by the HDD serial:

string drive = Environment.GetFolderPath(Environment.SpecialFolder.System).Substring(0, 1);
ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"" + drive + ":\"");
disk.Get();

string diskLetter = (disk["VolumeSerialNumber"].ToString());
string volumeCrypt = (Crypt(diskLetter.ToString()));

Console.WriteLine("" + volumeCrypt);

After that, the received data is encrypted by the Crypt method.
I would like to ask if there is a risk of hacking or bypassing this method?
