Good intro. I would be happy to answer any specific questions.

Note that Monero has been steadily increasing over the past 6 months to a year. While nothing as dramatic as the past few days, that steady progress set the stage for the latest fireworks. Over its 2 1/2 year history, the Monero project and technology has increasingly gotten positive comments and mentions from various experts in the cryptocurrency space and development has moved forward on some new items, specifically including a new GUI and a new protocol called Ring Confidential Transactions (which hides the amount of payments in addition to the sender and recipient).

Small correction:

Once the total number of Monero reaches 18.3 million. then money supply will stop decreasing

In fact once the total number reaches about 18.3 million, what stops decreasing is not the money supply but the rate of increase in the money supply.
