"""CLI for users to manage the wallet database and run research functions"""
#TODO:
# 1) Learn operating Blockscan APIs
# 2) Program functions pulling APIs data based on users interaction
# 3) CLI function to easy add new wallets and other data to the wallets_dict.json
# DONE - loop through each info separately
# DONE - ask to re-add info if matches
# DONE - ask for additional wallets for the same user
# DONE - add and print all the added wallets
# DONE - csv export (get away the line row)
# - Network choice on expoer csv option
# 4) Prints options for the user (-h)
# 5) Remove wallet option
# 6) Edit wallet option
