Bitcoin Mining explained.... looking for more explanations... as the penny slowly drops...

Came across this website which explained it. https://www.bitcoinmining.com/

So far out of everything I have read this seems to make the most sense...

Trying to get my head around crypto currencies is proving more difficult than I thought... it's all so virtual, there is nothing tangible I think that is the problem.

But the penny is slowly dropping... pardon the pun ;)
