I insist and repeat my statement:
The problem of course is not in the time of settlement as you have pointed. The problem is that in order to send a million dollars, you need to "own" a million dollars in XRP or you need to "borrow it" from an institution.
So now you are exposing the bank balance sheet to the volatility of XRP during the time that you own it or borrow it.
And i repeat to you once again, you have some very basic understanding wrong, and in all humility, one "DOES NOT" need to have 1 million ripples to send 1 million 'dollars'. One ought to have 1 million 'dollars' to send 1 million 'dollars'
Which is exactly i pointed out, when value of ripple comes into action. I hope the point gets across this time else you come of as really either not reading what is said, or perhaps strongly biased in your mind.
Bitcoin is purely store of value, it is so bad for transfer mechanism, with 4 days + ack time and confirmation times. Why ? it is not made for transaction, it is made for proving value by work. although the work is useless , which is an evolution to things like Etherium where work is promised contract code.
Anyway having that aside, still the funniest thing is ripple will probably be the most stable currency, because once it gains transaction properties in real markets, there will be large needs of reserve maintenance by various entities (market makers, FI's, central banks etc )
what part of my explanation are you NOT getting ?
and your have put borrowing xrp in a totally wrong sense, 'You' DON't borrow it for holding, it is 'BORROWED' on the RCL during the Byzantine agreement and consensus process to promise 'counter-party' ( which is what eliminated counter party risk ). This borrowing happens for 45 seconds at 'most'. current on-ledger confirmation is around 1000 tx/second. What are you taking about ?
Don't you see the clear definition of 'POOL' in the cost model PDF you have pasted above ?
I know its hard to imagine for traditionalist's who see a crypto-currency as a computerized form of 'piece' of something. but value can also be derived by properties and knowledge that is implemented in the mathematics that guarantees certain terms and conditions ( all consensus algorithms that guarantee 'counter-party' risk elimination )
you need to study and update yourself, and i am saying this not out of dis-respect, but you truly are getting things in a very naive and wrong manner. take time, study a bit.
good luck
