I've been dealing with crypto currency for about 6 months now an am fascinated with it.  I explain to my kids but they can not make sense of what I tell them on how it works and why it is so gnarly.   I was thinking about putting a miner rig here for them.  With a budget of 500$ and profit is split between two children where do I start?  I was told to just buy the crypto and let it accumulate.  That might work but its not so much the money, I want them to see the action done and then keep up with it seeing the coins put into there personal wallets every time it's payday.  Can anyone suggest or point me in a good direction.  I started here because bitcointalk seems highly recommended.
