What cause wow gold price high?

Yep, the shortage supply of wow gold cannot meet the demand and forces price up. Recently Blizzard have carried out a series of policies to curb account hacking so that some unscrupulous gold sellers who are close bounded up with account hackers can't obtain enough gold. This is why wow gold price rises so fast.

But I am not going to complain about the higher price compared with my account being hacked and my gold being stolen, because I am sick of account hackers who made me suffer a lot.
