The prominent US-based cryptocurrency exchange Kraken introduced its official iOS app back in 2014. All Kraken customers can use the app to trade Bitcoin and other digital assets on the exchange, read cryptocurrency news, and manage their personal account information. Unfortunately, the app hasn’t been much improved since it was first released, which is evident from its poor rating of only 1.3 stars out of 5. But despite the numerous harsh reviews the app has received, it covers all the basics, and its outdated design isn’t impossible to get used to.
Kraken has five verification tiers: from Tier 0 to Tier 4. Users who belong in Tier 0 are only required to submit their email, but they can’t do anything else besides looking around. Those who submit their full name, date of birth, country, and phone number are instantly promoted to Tier 1, which means they can deposit and withdraw in digital currency only. To get into Tier 2, users are additionally required to provide their address. Tier 2 enables deposits, withdrawals, and trades in digital currency to all users and fiat currency funding to users living in certain countries.
