Nigeria -- the world's second-largest Bitcoin market after the United States -- has banned the trading of cryptocurrencies. It's triggered anger among Nigerians who see cryptos as a safe haven in a battered economy.
Cryptocurrencies eliminate the need for banks and other financial intermediaries in managing exchanges of currency and assets.
Despite the technology being decentralized -- with no government, company or person controlling it -- the Central Bank of Nigeria (CBN) is cracking down on the trade of cryptocurrencies.
Last Friday, the CBN instructed commercial banks and other financial institutions to close accounts transacting with cryptocurrency exchanges.
Before the ban was introduced, Enogieru Osasenaga invested 100,000 Naira (€216, $263) in Bitcoin, the world's first decentralized digital currency. A week later, its value had doubled.
Dollar shortage and excessive controls
Osasenaga showed me on his phone just how much the trade in digital currencies has recently risen.
He said the crypto ban had taken a significant toll on his business.
"I'm unable to receive and send payments or procure electronic gadgets online. Because, of course, again, I cannot exceed the $100 limit on my Naira debit card," Osasenega told DW.
The CBN also asked banks to identify "persons and entities" operating cryptocurrencies within their systems.
Since July 2020, Nigerian banks have reduced the amount customers can spend abroad using debit cards.
Africa's giant economy faces dollar shortages due to the sharp fall in oil price, Nigeria's main export.
Local banks restrict transactions with hard currency -- mostly limiting customers to withdraw less than $100.
That's why Osasenega had to look for a way to circumnavigate the restrictions set by financial institutions.
Behind the ban
The CBN doesn't clearly state its reasons behind the crackdown, but some economy experts have an idea.
Shuaibu Idris, the managing consultant at Time-Line Consult, said the CBN had foreseen a potential crisis in the digital currency trade.
He said there was about $4 billion of assets embedded in cryptocurrencies in Nigeria.
"If the owners of these assets reside in China, Singapore, India, US, or Kenya come and take this money, what will happen to the economy of Nigeria? There will be a systemic collapse," Idris told DW.
"Then there's a potential systemic collapse arising from the price sensitivity that is exceptionally high with Bitcoin," he added.
It's not the first time the CBN tried to control cryptocurrency trade.
In 2017, it released a similar secular, but it did not stop the booming of cryptocurrency business in the West African nation.
Since then, Bitcoin trade volume in Nigeria has increased by at least 19% annually.
Estimates show that Nigerians have traded nearly $600 million in Bitcoin in the last five years, making it the second-largest Bitcoin market after the United States.
Idris doesn't believe the Central Bank of Nigeria can control how people conduct digital currency, no matter how many tough regulatory measures are introduced.
"We are having an enormous amount of currency restriction. People who want to trade are not able to buy dollars or foreign exchange to import the items," Idris said, adding that is the reason people have turned to cryptocurrency to remedy the problem.
"It's like a cat-and-mouse race."
The Nigerian economist said the number of so-called informal businesses in Nigeria numbered almost twice that of registered businesses, and billions of dollars were in circulation without the government's knowledge.
The recent ban will most likely make the situation worse and lead to a further fall in revenues.
Osasenega said he and other cryptocurrency enthusiasts will find a way around the ban.
"It's going to be around a couple of days or a week to circumvent this policy," Osasenega said, adding that "we don't necessarily have to use banks, and at the end of the day, it's the banks' loss."
