Keep in mind it's not as simple as mining Bitcoin.
Thank you so much at least we got some answers now have you personally mined steem. + can you mine steem power?
It's not that simple. To be rewarded with blocks (steem) you must be in the top100 witnesses. First post I linked to has where to find it.
In other cryptocurrencies like Bitcoin and ether your rank is determined by computing power alone, here while computing power has an impact on your rank the larger impact is people voting for you. Every account has 30 votes they can utilise (and take away and reuse) for witnesses. I am currently voting for 4 witnesses I believe contribute to steem ( I'm sure others also do but those are the witnesses that have created features that I personally use).
It's difficult to explain all this on my phone, when I get back from Holidays I can do up a post for you and your friends if you think there will be interest.
