title_body: Is there a minimum amount of ADA I can send in a transaction? Can I send 1 lovelace (0.000001 ADA) to another address or is there a minimum amount I need to send?
  Of course there will also be the transaction fee of (currently) ~0.16 ADA, so such a transaction would not make much sense in most cases. Still I'm curious if it would work.
upvoted_answer: There is a minimum UTxO transaction size of 1 ADA not including fees. That means the absolute minimum transaction is 1 ADA + fees.
