Mining of cryptocurrencies often require a pretty good investment in computer hardware and power consumption. But introduction of digital miners and mega-miners for mining of several Steem Engine tokens doesn't need anything but your investment.

However, I don't like to call those token distribution systems as miners but these days, this terminology is loosely being applied to many token generation systems including wagering in many gambling apps.

But here comes a breakthrough technology that enables everyone with a smartphone to mine cryptocurrencies without any upfront investment.

Sometime back I came across these interesting mining apps that do not drain your internet bandwidth and phone battery but keep mining cryptocurrencies 24x7 without any initial investment.

These apps takes only a few minutes to install and set-up. Nothing can get easier than this!

How does this sound to you?

Electroneum

Another cryptocurrency with mobile cloud mining feature is Electroneum (ETN). WIth this app, you can receive up to $3 USD worth of ETN every month. But this app requires you to complete KYC formalities. It even asks you to submit a couple of selfies to give access to your wallet.

If you're interested to get this app, here's my referral code for it:

While Pi needs a check-in every day, ETN only asks you to check-in every week. Rest of the time you can keep these apps closed but still continue to earn cryptocurrencies.

I really have no idea how popular and worthy these cryptocurrencies will get with time but it's a fun to mine them and build up on your crypto collection using just a mobile phone.
