What was the best/most interesting thing you bought with Bitcoin, when, where you bought it and how many Bitcoins it did cost? 
Directly with Bitcoin? I bought a second hand mobile phone to someone I know who accept Bitcoin as payment. I cant remember exactly how much Bitcoin it cost that time (early 2017) but the value equivalent to fiat is $80. Until now the phone is still working though depreciated due to the latest phones. But it has a sentimental value for me as one of the things I bought when I started to use and invest on Bitcoin.
