You simply follow this guide on androids, and also this guide I wrote to get your phones and computers Mining for transactions that are happening on the network for each coin. As you "find" transactions you may get some fractions of a coin, once you get up to say 1 full coin, you can transfer it to your own wallet, then use it, OR go to a market like exodus.io or coinbase and sell the coin on the exchange. I will write more blogs on these details in the coming days. Keep an eye out and upvote!
