Thank you very much and the only way to make money other than grinding spawner loot is bosses?
From what i see some main gameplay that have good income for early and mid game:
1. Grinding blazes, epic iron golem, or epic villagers for exp, mobcoins, stars, and some loots
2. Bosses battle for boss drops, exp, stars, and some mobcoins
3. Farming custom crops
I personally recommend bosses battle, for good rewards and more active gameplay, but there are some trick you need to know. Need to strengthen your armor and weapons with custom enchants for better fights too.
Grinding blazes and other mobs worth more if you can kill mobs very fast (there's a trick) and adding Inquisitive and other ce that increase your income of exp, stars, and mobcoins. But grinding can be very boring after long time.
Farming gives good amount of money too, so it's a good choice. But make sure to choose the good ones and you need the recipe to able to farm one kind of custom crops. You can also use some ce on hoe for farming.
Exp and stars can be used for buying ce books in /enchants, mobcoins for /transfer, but if you don't need them you can sell it to other players.
Other common method for making money:
1. Spawner grinder farm, but needs a lot of money (a lot), active or afking for long time near spawner, and best for island with multiple members to maximize the income from it. Best for mid to late game.
2. Cactus afk farm, similar to spawner grinder farm but far cheaper to build but requires a lot of time and effort to build. Best for early or mid game.
3. Visiting profit shops, good for beginners to make some money so that they can start a little farm or other activity.
4. Opening ce books and selling good books for good price, but based on luck and people's offer.
5. Killing other players in PvP area for loots that can be sold or used for better gears.
That might be too long but hope it helps
