Happy to help. Make sure you get them into alt-coins because 2018 will be the year of alt-coins. Bitcoin on top of being a piece of garbage, is also kind of mainstream now. Dash is exactly where Bitcoin was at the end of 2016. There are some smaller projects with much better potential growth like WTC, SONM, MCO etc.
For a mobile wallet I use jaxx.io because you can sync it on every single platform and it does feature many coins and it's easy to use. http://www.exodus.io/ is good for the PC
