I've managed to get some of my work colleges to setup an electroneum wallet on their smart phone and mine etn coins for free without any load on their phone cpu. While they didnt take it seriously as a means to really earn money like me and non of them was suddently interseted in investing in the coin like they know I did when it was less then a cent (I currently hold about 40k) They do quite enjoying the idea and seems to have fun from all of this so what I've started doing is integrate it into our daily money exchange - for example: We have a coffee machine at work but my boss is too miserly to also provide us with Coffee capsules and we need to buy them for our selfs so now whenever someone is out an needs a capsule he just need to pay 25 etn to the seller and get one! There's a real life implementation of crypto for you :)
