From the villages of Nusantara, an ancient yet influential region of Southeast Asia, there is a legend that everyone knows, from the mischievous kids in the kampungs to the elders passing down the tales in hushed whispers. It is the story of the Toyol.

For the uninitiated, the Toyol is a small, child-like spirit with green skin and big red eyes. It is not a typical ghost you read about or accidentally bump into; it is a ghost you hire. A master, usually someone desperate for wealth, summons a Toyol through a shaman known as a Bomoh and strikes a pact. The deal is simple: the Toyol will sneak into the houses of your neighbours, slip through cracks in the walls, and steal their money, jewelry, and gold, bringing it all back to you.

You get rich while you sleep. You get wealth without work.

But there is a catch. Just like anything that involves the supernatural. There is always a catch.

The Toyol requires maintenance. You must treat it like your own child, and you must feed it. Sometimes you give it milk or treat it with sweets, and sometimes, a few drops of your own blood from your thumb.

If you forget to feed it, or if you get too greedy and send it to steal from a house protected by stronger magic, the Toyol doesn't just stop working. It comes home, hungry and angry, and it eats you.

In the world of Web3 and cryptocurrency, we like to think that we are evolved. We think we are men of science and math. We don't believe in spirits.

But look closely at the "passive income" strategies of the modern crypto trader, and you’ll realise: We are still summoning Toyols. We just call them trading bots.

In the old days, you went to a graveyard with incense to summon your helper. Today, you just go to GitHub or a DeFi platform with an API key.

A trading bot (or an MEV bot/sniper bot) is a piece of code designed to do exactly what the Toyol does. It is small, invisible, and inhumanly fast. You give it instructions: "Watch the market. When the price of Ethereum dips, buy it. When it goes up, sell it. Steal the profit margins before the other humans can react."

Just like the folklore, the appeal is identical. You want to go to sleep and wake up richer. You want an entity to do the dirty work of staring at charts for 24 hours a day so you don't have to.

When you copy-paste that code or set up that grid-trading strategy, you are performing the modern summoning ritual. You are bringing an autonomous entity to life and commanding it to gather wealth.

Here is where the metaphor turns into a warning. Just like a Toyol is useless if it is weak, a trading bot is useless if it is starved.

In the spiritual world, the fuel comes in the form of offerings placed in or outside the home. In the blockchain world, the fuel consists of gas fees and liquidity.

Each time your bot makes a move, and every time it sneaks into the market to grab a profit, it has to pay a transaction fee to the network. If your wallet runs dry on gas (ETH, SOL, or BNB), your bot freezes. It gets stuck in the walls of the blockchain.

Worse, you have to maintain the parameters. The market is a living, breathing ecosystem. A bot that was profitable in a "bull market" (when everything is going up) is deadly in a "bear market" when everything is crashing.

If you set your Toyol loose in a village that has no money, it will starve. If you leave your trading bot running with old instructions during a market crash, it will keep trying to buy a dying asset, draining your wallet until there is nothing left.

The most terrifying part of the Toyol myth is when it backfires.

There are stories of masters who became complacent and lazy. They stopped checking on their spirit and offering the blood from their thumb. The Toyol will eventually realise the master is weak and will turn on them, sucking their vitality away until they are husks.

In emerging tech, we call this liquidation or the bug exploit.

Imagine setting up a high-frequency trading bot with leverage, which is actually borrowed money. You go to sleep, dreaming of a new car. While you are dreaming, the market dips by 15%. A human trader would notice this and immediately sell to stop the loss.

But your bot? Your bot is just a script. It follows the old rules. It tries to buy the dip. It borrows more money to double down. It misinterprets the data.

By the time you wake up and check your phone, the notification screen is red. Your balance is zero. The bot didn't just fail to make money; it aggressively lost everything you had because it didn't have a conscious human guiding it.

The spirit has eaten the master.

Does this mean we shouldn't use bots? Does it mean we should fear automation?

No. The lesson isn't "don't use magic." Legendary warriors and kings are often known for their magical items, like Hang Tuah’s Keris. The lesson here is about respect and mastery.

A powerful Bomoh controls the Toyol; the Toyol does not control him.

As we adopt these new technologies like AI agents, algorithmic trading, and automated farming yields, we must remember that they are just tools, not replacements for human judgment. They amplify our intent. If you are greedy and lazy, they will amplify your ruin. If you are disciplined, educated, and watchful, they will build your empire.

So, by all means, code your bots. Set up your passive income streams. Summon the digital spirits to do your bidding.

Just remember to check on them. Remember to feed them. And never, ever think you can turn your back on them completely.

Because in the machine, the Hantu is always watching.
