If I didn't trust my wife, I would be dead. That doesn't mean I trust your wife. If you don't see the difference, then this is a lost point to argue. Liquidity is not universally recognized. I can say the same thing: "The difference between your IOU's and mine, is that mine are liquid and yours aren't."
You
could say it, but you'd be lying. Yours are locked in a centralized exchange. If they decide to halt withdrawals, you're screwed. If mine halts withdrawals, mine remain liquid, thus I can still trade them. They'll likely be worth a lot less but still liquid nonetheless.
An exchange is centralized by definition.
I'm curious about where you looked up that funky definition. Source?
A decentralized exchange is a misnomer, they are distributed exchanges, but they still require trust and are centralized to a lesser degree.
How about the OTC market?
How about the black market?
How about the food chain (is god doing the arbitrage between supply and demand)?
How about Ripple? Ah, yeah, we've already mentionned that one...
Ripple's built in distributed exchange doesn't require any trust at all and is decentralized.
What requires trust in Ripple is the redemption of IOUs, but that has nothing to do with the exchange in itself.
You could start a day-trading business with the XRPs you get from a giveaway, and grow your stash by trading currency pairs on the distributed exchange without *ever* going through a gateway. Everything you would do would then be perfectly decentralized and trustless given the fact you just don't care about being able to redeem your IOUs.
Liquidity is a function of the the risk.
Again, that's a very exotic definition of liquidity, but I guess you must have an equally exotic definition of risk that makes it fit all together. Source?
They'll likely be worth a lot less but still liquid nonetheless.
Or nothing. You could say Bitstamp has more liquidity, but to me in China, you'd be lying. It's a matter of perspective.
Liquidity isn't a subjective quantity. It is an objective quantity based on the quantifiable availability of supply and demand for a given asset, that would allow you to open or close a position.
What Coinseeker is telling you is that, if you hold the debt of an exchange (be it Bitstamp or BTCChina) as a balance
at that exchange, and the exchange decides to suspend withdrawal, you have no way to sell back that debt and get back your funds since the exchange who is the only possible counterpart isn't buying back the balance (aka. not allowing you to redeem it to real assets). In other words, you are screwed. But if you hold debt of an exchange as Ripple IOUs, even if the exchange decides to suspend withdrawals, you will still be able to sell your IOUs on the Ripple internal market to third party participants. You will suffer a mark down due to the situation, but you'll still be able to close your position.
So to make a long story short,
If you are using Ripple to hold your exchange balances:
- when there is no problem at the exchange, the liquidity of your assets = liquidity at the exchange + liquidity in Ripple.
- when withdrawal are suspended at the exchange, the liquidity of your assets = liquidity in Ripple.
If you are holding your balance directly at the exchange:
- when there is no problem at the exchange, the liquidity of your assets = liquidity at the exchange
- when withdrawal are suspended at the exchange, the liquidity of your assets = no liquidity at all
You can see that no matter how you look at it, balances held as Ripple IOUs are more liquid than balances held at the issuer exhange. It's not even a matter to debate, it's just a hard fact.
