Please, explain me, clear and exact

There was a story, called Ripple. It's a big book, lots of pages. I didn't read, but got advice from somebody I trust with my life. I bought around 35k coins last november, on a coin average of .59... Yes, I was lucky, but this friend said trust me, but learn it yourself. I have been reading, listening and watching a shitload of info.

I understand what a crypto coin is. I totally get the way XRP can change things! I kinda get what a blockchain is (barely 🤣). I understand what a stablecoin. I have no clue about the ETF's.

Could somebody take the time to explain this on childs language, and most important, how the price of a XRP coin can rise, if a stablecoin is used, or how a ETF van change a price.

I do sincerely believe in the Ripple company, and XRP is the coin nobody believed in, my guy had been in since '17, and he is as serious as can be.

I want to know more about the stuff around the XRP and Ripple, please enlighten me🤩🪙
