Counterpoint: blinking lights are in fact installed on airplanes both large and small. Red beacon lights blink, and so do high intensity white strobe lights. The variation helps identify the source of lights against a busy city skyline at night (that must be an aircraft we're looking at) and serves to call attention against a sea of steady lights in the background. It's very easy for the airplane to blend in otherwise. Even some racecars pulse their brakelights automatically to draw the attention of fellow racers. Finally, as a driver in sometimes poorly lit areas compounded with a rather avid local bicycling culture, I have found that bicycles equipped with rear-facing red blinking LEDs really help distinguish the bike against the background. The best setups had a light on the back of their helmets as well, which does the most to aid depth perception.

It's better than SMS, but relies on proprietary code implemented by multiple telcos. In my opinion, Signal is usually the best choice for most people. It works for messaging as well as calls. I would trust it over any of the other mainstream choices because it's open source and is run by a non-profit devoted to protecting privacy.
Caveman "restaurant"? This kind of a conversation usually takes place outside a restaurant after a business lunch.

My guess from context clues:
Prospective buyer: "One drugs pls to this shipping address." Seller: "0,05 ETH please at this wallet address" Prospective buyer: "Test amount sent, pls verify" Seller: "I see your test amount. Shipment will be sent once full amount clears" Prospective buyer: "Thx for verifying. Remainder on its way." Seller: "I see it, thank you for your business. Shipment of one drugs will arrive in two to three weeks. Enjoy!"
I imagine these sorts of messages between buyers and sellers which are hosted on the platform would be the PGP encrypted messages in question.
Rather ponderous, isn't it?
This sounds very similar to Arthur C. Clarke's Rama trilogy!
It detunes the pattern buffers.
