The Coin in His Phone

Desmond nearly dropped his phone into a bowl of pepper soup when the screen flashed red.

“Minus twelve percent?” he shouted.

The man sitting opposite him at the restaurant looked up from his newspaper. “Young man, did your wife leave you?”

“I don’t have a wife.”

“Then your crypto has left you.”

Desmond stared at his phone. The number had fallen again.

For three weeks, he had been a graduate trainee at Meridian Trust Bank, where he wore a stiff tie, smiled at customers who called him “my son,” and nodded intelligently whenever senior bankers discussed things he only half understood. He could explain fixed deposits, savings accounts and transfer limits. But crypto? Crypto was where his intelligence went to die.

Still, everyone seemed to be making money from it.

His cousin had changed his WhatsApp profile picture to a man standing beside a car that probably belonged to someone else. His former roommate kept posting rockets and moon emojis. Even Chidi from the office cafeteria had announced that he was “diversifying his portfolio,” although Desmond was ninety percent sure Chidi thought diversification was a new type of football formation.

Desmond had bought his first cryptocurrency three days earlier after watching a twelve-minute video titled THIS COIN WILL EXPLODE!!!

It had exploded.

Unfortunately, it was his money that was on fire.

The next morning, Desmond arrived at the bank early and marched straight toward Mr. Adebayo’s office. Mr. Adebayo was the branch manager, a calm man in his late fifties who had spent so many years in banking that he seemed personally offended by unnecessary excitement. Desmond found him arranging papers on his desk with the seriousness of a surgeon.

“Sir, please, can you explain crypto to me?”

Mr. Adebayo looked up slowly. “Good morning, Desmond.”

“Good morning, sir. Crypto.”

“Have you lost money?”

Desmond sat down. “I would prefer not to answer that question.”

“Then you have.”

Desmond sighed. “I bought something called Galactic Shiba Rocket.”

The manager removed his glasses. “You bought it because?”

“The name sounded ambitious.”

Mr. Adebayo put his glasses back on. “Excellent. Next time, buy something called National Goat Holdings. At least goats are real.”

Desmond laughed despite himself. “Sir, I’m serious.”

“So am I. Let us start again. What do you think cryptocurrency is?”

“Money on the internet?”

“Not bad. But let us say it more carefully. It is a digital asset that can be transferred electronically. Many cryptocurrencies use a system called blockchain to record transactions.”

Desmond nodded, then frowned. “So blockchain is a company?”

“No.”

“A bank?”

“No.”

“A very serious app?”

“No.”

Mr. Adebayo pulled out a sheet of paper and placed it on the desk. “Imagine everyone in your street keeps a copy of the same record book. Whenever somebody sends something, the transaction is added to the book. If one person tries to secretly change his own copy, the others can see that it no longer matches.”

Desmond leaned forward.

“That shared record,” Mr. Adebayo said, tapping the paper, “is a simple way to think about blockchain.”

“So nobody owns the book?”

“In some systems, no single bank or company controls it in the traditional way.”

Desmond’s eyes widened. “That is actually interesting.”

“Yes. Crypto is interesting. That is one of its problems.”

“What does that mean?”

“Interesting things make people forget to ask boring questions.”

Desmond looked back at his phone.

Mr. Adebayo continued. “When you use a bank, you know there is an institution between you and certain transactions. In crypto, depending on the asset and platform, you may be responsible for your own wallet, your own private keys and your own decisions. Lose access carelessly, and there may be nobody at a branch waiting to help you reset everything.”

“Private keys?”

“Think of them as proof that you control access to your crypto. Not your birthday. Not your mother’s maiden name. A private key must be protected.”

Desmond immediately opened his notes app.

Mr. Adebayo slapped the desk. “Not there!”

Desmond nearly jumped.

“You are learning quickly,” the manager said.

Over the next week, Desmond stopped buying anything. Instead, he read. He discovered that Bitcoin was not the same thing as every other cryptocurrency, that crypto exchanges were not all equally trustworthy, and that a digital wallet did not mean a leather purse for tiny invisible coins. He learned that prices could rise violently and fall with the enthusiasm of a politician denying a rumor.

Then, on Friday evening, his cousin called.

“Desmond! This is the one!”

“What one?”

“A new coin. Everybody is entering.”

Desmond was lying on his sofa, eating roasted groundnuts.

“What does it do?” he asked.

There was silence.

“Bro, don’t think too much. It is going to the moon.”

Desmond smiled. “What does it do?”

“People are buying.”

“What does the project actually do?”

His cousin sighed. “You have changed since you started working in a bank.”

Desmond sat up. On his screen was the exchange account where the remaining value of his Galactic Shiba Rocket was displayed. It had fallen so much that he was considering framing the screenshot as a memorial.

He remembered Mr. Adebayo saying, “You do not have to understand everything before you invest. But you should understand what you are buying well enough to explain it without hiding behind excitement.”

Desmond opened the information about the new coin. He read the website. Then he read it again. Most of the page was rockets, dogs and a promise to “revolutionize the future of decentralized happiness.”

He closed it.

“Are you buying?” his cousin asked.

“No.”

“Why?”

Desmond threw another groundnut into his mouth. “Because I have finally learned something.”

“What?”

“Not knowing is cheaper than pretending to know.”

His cousin laughed. “You’re becoming boring.”

“Maybe. But my money is sleeping peacefully.”

Months later, Desmond still knew far less about crypto than the loudest people online. He never became the office crypto expert, never posted rockets, and never called himself a blockchain entrepreneur. He simply kept learning before acting. Sometimes he bought small amounts of assets he understood. Sometimes he did nothing at all.

And, strangely, doing nothing became one of the smartest things he had learned.

Mr. Adebayo noticed.

“One day,” the manager said as they walked through the banking hall, “you may become a good banker.”

Desmond smiled. “Thank you, sir.”

“But first,” Mr. Adebayo added, “please explain to me what Galactic Shiba Rocket does.”

Desmond stared at him.

“Sir,” he said carefully, “I believe its primary function is to embarrass me.”

Mr. Adebayo laughed so loudly that two customers turned around.

Lesson

Crypto is not magic money, and popularity is not understanding. Before putting money into anything digital, exciting or mysterious, learn what it is, how it works, where it is stored, what risks you are taking and whether you could explain it in simple words. Sometimes the smartest investment decision is not buying quickly—it is learning slowly enough to know when to walk away.
