Can I send large amount of BTC (from 3 BTC) on bc1 addresses or better to use segwit (that start with 3) addresses?
Thanx in advance
Bitcoin use UTXO (Unspent Transaction (TX) Output), where every bitcoin transaction sends from at least zero address to one or more addresses.
they are no differance if you want to send it from Legacy address, segwit (that start with 3) address or bc1 addresses.
bc1 addresses save some
