Hey there! First off, if you would like to suggest an idea for an official guide to be made, you can make a suggestion here:

Secondly, when it comes to getting rich in OP Prison there isn't really a trick. There are many different currencies but they all have just about the exact same way to go about increasing your currency,
MINING. There is no shortcut, you just have to mine, mine, mine. Here is a very brief way to increase the currencies:
Tokens: Mine, increase the Greedy enchant
Beacons: Mine, increase the Swordsman enchant
Coins: Mine blocks in the abyss
EXP: Mine with the Expertise enchant, Use the quarry
You can get better picks via seasonal crates.
I have also actually made an unofficial OP Prison guide which you can view here:
https://pika-network.net/threads/op-prison-guide.568383/
It was made last season, and there is some outdated information in there. Some specifics such as last season's seasonal items, and enchants are slightly off, but for the OP Prison basics that guide should cover just about everything you'll need to you.
If there is enough desire for a new OP Prison Guide to be made, I can update that one, however I haven't seen enough new players to OP Prison asking questions to where I have gone in to update it yet.
If you have any other questions, feel free to ask me, have fun on OP Prison!
