I demoed [0] receiving one tenths of a cent's worth of bitcoin (0.00000010 BTC) instantly, and on Bitcoin's mainnet (not a test network).
I also demoed [1] purchasing swag from Blockstream's store [2] which is powered by their newly released Wordpress e-commerce plugin [3] that enables Lightning payments.
I did not screencapture the videos because Qubes dom0 does not come OOTB with screenrecording software, and I don't want to enable networking in dom0 to install software that does.
