1. Electroneum

Electroneum is a strong cryptocurrency designed to be mined from phones. It was already created in the year 2017 and at the moment of writing, there is over 3 million registered people. Electroneum offers you an easy interface you can work from. Every week, you will be required to reenable the mining proccess, but it's free and it doesn't require too many resources. That's why it was designed for phones.


2. Pi Network
Pi Network was launched in March 2019. It has quickly gained a big popularity and this app is still being promoted more than Electroneum. Unlike Electroneum, it yet can't be withdrawn and exchanges for fiat or other cryptocurrencies. Pi mining doesn't depend on how powerful your phone is. Your mining hashrate depends on the amount of bonuses you have applied and on the number of active affiliates. Pi is currently free to mine and after reaching the Phase 3, it will be withdrawable and transferred to a full, decentralized blockchain. It is, however already tradeable in the marketplace for goods and services.
