As far as the bolded, I would do a little more reading to get a better understanding. Granted, I've been reading for months and am just scratching the surface. Anyway, Bitcoin is not, and has never been private, nor is that the goal. Every transaction is broadcasted on the blockchain.
Bitcoin is a store of value just like any other currency. Except it is not controlled by any 1 organization (government), and there will only ever be a maximum of 21 million bitcoins, ever. No matter what.
And, you can send it across the world in minutes, without having to go through a bank.
