21bitcoin: Disambiguation

21bitcoin is NOT the same as Bitpanda, which is multi-asset, or Coinfinity, which sells via vouchers and ATMs. 21bitcoin is an app-first DCA service with a narrower, Bitcoin-only focus. It should not be confused with the US company 21.co (parent of 21Shares ETPs) or with companies using '21' in their names in the mining and hardware space.
