The best way to learn how to make gold in Diablo 3 is by listening to players who's goal is to make real money from playing Diablo 3. Why waste time trying out new strategies and doing your own research when other players have already done it for you? Markco, formerly of the popular WoW blog Just My Two Copper, has put hundreds of hours into playing Diablo 3 and has put together one of the best Diablo 3 gold guides out there. Right now, the price is only at $27 and includes three months of access to a private forum where dozens of Diablo 3 entrepreneurs discuss gold making strategies.
I have been a member of Markco's site since April of 2012 and have found the forum to be a goldmine of information. The gold guide has some great strategies and some very useful information and Markco has continually updated his guide based on his own research and the research of other Diablo 3 "pros" that are members of the forum. His guide is a "living document" meaning that it will be updated on a regular basis as new strategies are discovered. Honestly, the best thing about purchasing his guide has been having access to the gold forums. There are dozens of extremely intelligent individuals who are making tons of money playing Diablo 3, and most of them are members of Markco's forum. Access to the forum is worth the price of the guide.
Bottom line - buy Markco's guide now and get a jump start on making gold in Diablo 3. I am well on my way to making money playing Diablo 3 thanks to the strategies that I have learned from Markco and the other experts on his forums.
