It is difficult to make money D:

You can always sell gold/iron ore at /market to make money (also dia ore if you have a silk pick)

But that's the only way to get money...
There should be other ways, other than mining, especially on PvP (might be solved with the player market but it still won't get new money into the economy, just circulate it more). If the only way to make new money is to mine, it would turn this server even more into a survival server.

My point is, pls add more ways to get money, even if you admins/owners want the main way to get it by mining.

Survival was tweaked so that it is incredibly difficult to become wealthy. this was intentional, to prevent the massive inflation that survival usually has on other servers. If you wanna sell items to players, you gotta sell things that they really want (like enchanted books for example).

The reason why the old market was torn down was because getting money was really easy. The owners did not want that to happen. Anyways, you don't need money to survive at all. You can always get your own things; money is just something extra but not a necessity at all. There are many ways to get money, and I would think the best way is to make your own shop (make it at your own claim if you don't have enough money at /warp shop). All in all, I think the market system is doing fine because this is a survival server, not really a economy server.

Most people, including me, use money only for repairing.

They dont want tons of multimillionaires and they want players to have more interaction, this new market allows for both the players to take an active role and to keep from going stale because of millions of dollars flooding the economy.
The problem with economy servers where its easy to make money; once you get a million you have so much there is nothing really left. You can always get millions for little to no work and it becomes stale on the server. The community doesnt get a chance to grow as the server market is much simpler then running around trying to find lowest prices to buy stuff/ highest (or any) to sell at. Like Blue said in this thread, its not that people dont buy, its just making sure you are providing stuff players want/need.

Both Lion and Blue have valid points, most players want to be self-sufficient so selling wheat and carrots wont likely get much business, but nearly everyone has that one task they loathe. Wood and stone/cobble, while they dont bring in much are common sellers simply because cutting trees and mining are usually the one thing players hate doing. Selling harder to obtain items or ones that require more work, like enchantment tables and bookshelves, and like Blue said, enchanted books are always popular.

On Survival there is also cubeclimber which upon winning rewards $500 and on both servers catching weighted fish rewards money.

Really it doesnt require major work to make money, just a rethinking of how everyone is accustomed to going about collecting and using ores.

^ This.

Try to get a decent enchanted fishing rod and go fishing (heaviest fish can be caught in ocean biomes)
Easy money.

Also, you don't just have to sell items to players! Services are a good income too! For example, I made the majority of my wealth off of building for others. Figure out something that the players don't want to do and you can likely make a profit off it!
