HONG KONG — Getting your head around cryptocurrencies was hard enough before governments got involved.

But now that policy makers around the world are drawing up fresh regulations on everything from exchanges to initial coin offerings (ICOs), keeping track of what’s legal has become just as daunting as figuring out which newfangled token might turn into the next Bitcoin.

The rules can vary wildly by country, given a lack of global coordination among authorities.

And while that may change after finance chiefs discuss digital assets at the Group of 20 meeting in Buenos Aires this week, for the time being there’s a wide range of opinions on how best to regulate the space.

Below is a rundown of what major countries are doing now.

ASIA
Most of the world’s cryptocurrency trading takes place in this tech-savvy region, with Japan playing a dominant role after it introduced a licensing system for digital-asset exchanges last year.

In Hong Kong, regulators have adopted a more hands-off approach while at the same time warning crypto platforms to refrain from trading anything that qualifies as a security without permission.

Singapore’s deputy prime minister has called cryptocurrencies an “experiment,” adding that he doesn’t see a strong case to ban trading.

Taiwan authorities are taking a wait-and-see approach, while the Philippines plans to roll out rules for ICOs by year-end.

China, once a global hub for cryptocurrency trading, now leads the world in cracking down. It has outlawed digital-asset exchanges and ICOs, blocked online access to overseas trading platforms and cut off power to Bitcoin miners.

South Korea, which became a hotbed of cryptocurrency activity last year, is also tightening oversight as it works on a comprehensive set of regulations, though it has allowed exchanges to keep operating for now.

In India, where crypto-mania has been relatively subdued, the government has said it doesn’t consider digital currencies to be legal tender and will take measures to curb their use.

AMERICAS
Most cryptocurrency trading in the United States takes place in a legal gray area, a point highlighted by the nation’s two top market watchdogs in testimony to Congress in February.

Still, the Securities and Exchange Commission has been scrutinizing everything from ICOs to cryptocurrency hedge funds and trading venues. How exactly it plans to crack down on the industry remains to be seen.

In Canada, regulators have said that ICOs may be treated as securities and that products linked to cryptocurrencies should be considered high-risk. At the same time, the country’s stock exchanges have become popular destinations for crypto-related stocks and exchange-traded funds.

Brazil’s market regulator, meanwhile, has barred funds from investing in cryptocurrencies because they aren’t classified as financial assets.

EUROPE
The European Commission is still reviewing the bloc’s regulatory framework for cryptocurrencies.

The European Securities and Markets Authority, which coordinates standards across member states, has proposed restrictions on derivatives tied to virtual currencies for retail investors, and is also assessing how the European Union’s new MiFID II rules apply to digital assets. One regulation that’s already in the pipeline: platforms that exchange virtual currencies for conventional money will soon have to verify the identity of their customers.

At the national level, Germany has cracked down on trading venues that lack permission to offer brokerage services and French authorities have said that online platforms for crypto-derivatives should face tough reporting and business conduct standards.

In the United Kingdom, a parliamentary committee is looking at how to police digital currencies.

Russia’s finance ministry unveiled draft legislation in January that would ban cryptocurrency payments while allowing ICOs and the exchange of virtual currencies into the traditional sort. To make the rules permanent, the ministry may have to overcome opposition from the nation’s central bank.

AFRICA
It’s mostly a gray area for cryptocurrency regulation in major African economies.

South Africa’s markets regulator doesn’t oversee virtual currencies or digital-asset exchanges, though the central bank has said it will investigate an “appropriate policy framework and regulatory regime.”

In Zimbabwe, where digital currencies are traded on exchanges and used for remittance payments, the monetary authority has warned about the risk of “money laundering, terrorism financing, tax evasion and fraud.”

It’s a similar story in Kenya, one of Africa’s most tech-savvy nations. There, Bitcoin and other cryptocurrencies have grown in popularity even as officials have warned against trading them.

In Nigeria, cryptocurrency markets aren’t regulated, but the central bank, which likens Bitcoin trading to gambling, has said that will probably change. — Bloomberg
