The ONLY thing???
Lol, if thats what you think, then maybe this really is not coin for you
I really don't believe that banks out there need XRP's, *or* any external system for transfers.
I mean.. can't you *already* wire transfer from any bank to any other bank?
Sure, bank transfers are slow. But it's not for technical reasons that a bank transfer takes several working days (if that was the case, to start with, they would take 3 days, not 3 *working* days, and delays would accumulate).
Costs? SEPA transfers are already free. Accross continents, no, but the problem is that transfers accross continents generally involve costy conversions, anyway.
I don't know why banks out there would need XRP's, nor Ripple's technology, really.
Ripple's technology is a classic centralized system. Is that crap? No, of course not, it's even much better than decentralized, technically-speaking. But it's old, it's how everything already works.
Is the only appeal that it'd be a buffer between banks, that no bank really owns? Well..
Whats problem with Bitstamp btw, I use it for fiat-XRP transactions, didn't have problems so far
Many have sent (even though I now believe I had picked the right address) XRP's to their "IOU" XRP address, funds have been frozen there for weeks.
New users are waiting to get verified for a month now (but that's normal), and people are waiting for their fiat deposit/withdrawals for a month (that's definitely not normal).
(& yes, they have made their IOU XRP deposit address clearer now, but it wasn't like this a week ago)
