I am holding legacy.
Confused, should I go segwit for seemingly lower fees?
Pros and cons of each?
Can you go back and forth?
The initial BTC address is regarded as a legacy address, while SegWit is a newer address format with lower fees.
Segregated Witness (SegWit) stands for "separated witness," with "segregated" meaning "to differentiate" and "witness" referring to the transaction signatures involved in a particular transaction.
