Ihr Geld ist nicht weg, mein Freund, es hat nur ein anderer.
Your money isn’t gone, my friend. It’s just that someone else has it.

Good info above - thanks. I'm glad to hear the commmitment to Whonix is strong.
Since the German post office doesn't accept international money orders anymore (I checked), that's a bummer.
But, a Whonix 'birthday card' ("Dear Patrick, Hope you are enjoying your 40th birthday!" ) with a couple of crisp bills should be very doable!
I note it is NOT illegal to send cash in the mail in/to most jurisdictions (Germany included). Further, following this advice below for sums that are not enormous should be a reasonable risk instead of running the Bitcoin gauntlet:
How to send your banknotes
If you are sending banknotes, put them in a promotional flyer or wishing card. Use a nontransparent (opaque) envelope. If you are sending many notes, think about using a cardboard envelope or padded envelope.
How to send your coins
When you send coins, make sure to package them so that they cannot slide or ring. One way to do it is to fix the coins with adhesive tape to a piece of cardboard. Alternatively, if you send more coins, you can usecoin wrappers or aluminium foil. If you send coins in a parcel, make sure to fill up the empty space with light materials, like plastic bubble wrap, foam, krumpled up newspapers or polystrene packing peanuts.
Is it legal to send cash?
In most countries it is perfectly legal to send money in the mail. In many countries it is common practice to put a few banknotes in a birthday card and send it in the mail.
In the United Kingdom, the United States and in most European countries it is legal to send money in the mail, also if the money is sent overseas.
In some countries there are restrictions on sending money in the mail. These countries have laws in place that either forbid sending money through their postal network, or limit it to a maximum amount.
If your country is in the list, please consult the applicable laws before sending money in the mail:
Central African Republic
China (except Hong Kong and Macao)
It's OK to tape your envelope
When you send coins, or a stash of banknotes, it might be a good idea to tape your envelope. It is perfectly OK to tape an envelope: the seal, edges and/or the corners are most vulnerable.
If you write your address on the back of the envelope, and cover it with transparant tape, it will be easy to see if the envelope has been tampered with, which is a strong deterrent against tampering.
Check the postage prices
Make sure you pay the full postage. If you don't, your letter or parcel might be sent back because of postage due, or left for collection in the post office.
IF NECESSARY [probably not in Whonix case], include a return address to which your shipment can be returned. The address can be a PO box or a regular address. It is not mandatory to include your name in the return address. The return address is either written on the back of the envelope (Europe) or in the upper left hand corner (United States).
