I'm a semi-retired engineer looking for some ways of earning a little on the side and using cryptocurrencies seems like a good way of doing it :)

I'm limited to 510 characters for a description, so I'll waste a few making that comment. What else? There's a ton - are Big Bang and Cyclic Universe theories logical illusions? What forms of mathematics create beauty? Coffee, tea or a chocolate bar? ... or maybe what would an ideal partnership with someone be like? I'm both a "couch surfer" and explorer ... where might you like to go? I'm wishing us all the best.
