I totally agree that Ripple is overextended, as are most other currencies. Ripple does have strong points, starting with speed and cost of transaction processing. The fact that supply is expanded each month may become irrelevant as market capitalization grows continually with wider use. The primary negative I see with XRP is centralized mining, and question whether this is scalable with extensive volume in the long term. Open ledgers with other currencies will always present a scaling problem in the long term, and will need an answer.
Thank you for your continued commentary and perspective.
