Hi guys,
Thank you to all who have answered and pitched in. It's greatly appreciated.
As new account I cant reply to each of you as it would take forever but again, thanks!
1) I understand the importance of private keys being absolutely private (showed them bitaddress and how they can download the code and run while wifi is off) and students would only show the public key...I mean if they dont learn in our school to refrain from displaying their private keys in public then we have failed them

2) Doge for the win...will set that up and see how that goes along with running Electrum. I think I will send them $1 each out of my own pocket but would love any links to safe faucets...some of the faucets I saw back in the day seemed a little sketchy
3) The janky gpu miner will get them some sats as well and they are seeing, on the screen terminology like epochs, shares, rejections, difficulty, stratum, etc
They also get to experience the heat/power needs for a discussion on the environmental impact
4) We are also discussing briefly the economics of BTC...although its not part of the case study as its focused on the tech side of things, I felt its important for them to know
Again, thanks for the input
