#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
# - loop through each info separately
# - ask to re-add info if matches
# - ask for additional wallets for the same user
# 4) Prints options for the user (-h)
