Hello! This week we’re getting our heads around the mind-boggling world of digital currencies. The Guardian’s UK tech editor Alex Hern answers our questions about Bitcoin — from how it actually works to its extraordinarily high energy use. Josh Ryan-Collins from UCL tells us why the Bank of England is exploring introducing its own digital currency. And Rachel Statham from IPPR explains why the discussion about the future of money shouldn’t ignore the role of cash.
AND we chat to Ray Hopkinson from environmental charity Hubbub about an exciting new bike library being trialled London.
