Is there a way or command you could recommend to sort or isolate Base58 (legacy) addresses from the TSV sheet > to a data.txt file?
Use
grep:
grep "^1" blockchair_bitcoin_addresses_and_balance_May_22_2024.tsv > legacy_and_balance.tsv
I did it for you:
legacy_and_balance.tsv (file will be deleted in 24h).
