I really did the last days.

I also spent REAL money (10BTC) to buy some K's of XRPs, just to test their bult-in trade system.

And I'm convinced it's a fucked up system.

Not because is not useful (it is useful)

Bad because it is:

a) everything Bitcoin was designed to address (trust-based system, WTF man? Bitcoin very first purpose is to address the need of trust in money transmitting)
b) a premined scam

And no, Adam, NO: it won't do any good to Bitcoin. Users of Ripple may realize that the fiat currencies their are exchanging are just valueless IOU0's, a debt ticking-bomb about to explode, so they may prefer the crypto, as we prefer BTC to USD - but the crypto they will prefer is XRP, 100% premined by a private company.

Trust the blockchain, trust your private keys, trust bitcoin. Not a private coin on a system based on trusting third-parties (firstly and foremost OpenCoin; then, your Gateways).

And think about this: OpenCoin will hold to 50% of the total Ripples created. You need to grant them a LOT of trust to place money in XRPs. They can crash the market with a fart, and they may be very well decide to hold onto 80% on the XRPs. Or to 90%. They won't tell you, because they don't know, they will just do what it suits best to them.

Now compare that shit with BTC, my friend.
