Bitcoin Q&A: Coin management and change

How do I construct a transaction with multiple inputs? Which wallets offer coin selection / management features? Explain the concept of change.

Take a look at Chapter 6 of ‘Mastering Bitcoin’: https://github.com/bitcoinbook/bitcoinbook/blob/develop/ch06.asciidoc

These questions are from the third and sixth session of MOOC 11, which took place on February 14th and March 7th 2019, respectively. If you want early-access to talks and a chance to participate in the monthly live Q&As with Andreas, become a patron: https://www.patreon.com/aantonop
