LPH - No doubt Geoinvesting didn't have the same problem. Since that now forgotten stock symbol for the hog farm company went dark personally I wouldn't even touch Baidu. There are plenty of ways to get exposure to China without buying Chinese companies.
I made some nice coin on LPH as I'm sure many did but it goes to show that at best they are a very short term trading vehicle and probably belong more on those types of boards IMO
