perhaps i spoke too soon -- had mini heart attack when i saw this
Why? Because you can arbitrage to make more than 500% profit? 
i naturally assumed coinlab had blown up mt.gox and all was lost -- i'm way, way overexposed in btc; don't want to have to hit those mean streets again

Payment has never been a problem, you have no idea how Bitcoin-friendly Alipay(every Chinese network user uses it) is, compares to Paypal, at least until now.
Think of BTCChina as another BTC-e, no public relation and never felt the need to do it.
the question was raised before -- is alipay reversable like paypal? i know EVERYONE uses it, however, i never have (always wanted to try out taobao)
Centralized systems are always reversible, I think there is no exception. The reason I feel safe about using Alipay is that they are way too large to notice the Bitcoin economy growing on it, even if they crack down on one exchange people can always switch to something else, we have been buying VPNs for circumventing GFW after years of government prohibition hardly with any problem.I am actually more worried about an exchange default atm.
