The type of cryptocurrency wallet you should use depends on what kind of cryptocurrency you are storing, your security needs, and your preferences. Generally, most cryptocurrency users recommend using a “cold” or “hardware” wallet for long-term storage, and a “hot” or “software” wallet for short-term, day-to-day trading. Popular cold wallets include the Trezor, Ledger Nano S, and KeepKey. Popular software wallets include Coinomi, Electrum, and Exodus.
