What can Rio 2024 really achieve in Biden’s final act, before the new show rolls into town?
Climate change, the crisis in the Middle East, the continuing war in Ukraine, combating global poverty.
All of these are critical issues for Britain and beyond; all of them up for discussions at the G20 summit in Rio de Janeiro this week, and all of them very much in limbo as the world awaits the arrival of president-elect Donald Trump to the White House.
Because while US President Joe Biden used Nato, the G7 and the G20, as forums to try to find consensus on some of the most pressing issues facing the West, his successor is likely to take a rather different approach. And that begs the question going into Rio 2024 about what can really be achieved in Mr Biden’s final act before the new show rolls into town.
On the flight over to Rio de Janeiro, our prime minister acted as a leader all too aware of it as he implored fellow leaders to “shore up support for Ukraine” even as the consensus around standing united against Vladimir Putin appears to be fracturing and the Russian president looks emboldened.
“We need to double down on shoring up our support for Ukraine and that’s top of my agenda for the G20,” he told us in the huddle on the plane. “There’s got to be full support for as long as it takes.”
But the election of Mr Trump to the White House is already shifting that narrative, with the incoming president clear he’s going to end the war. His new secretary of state previously voted against pouring more military aid into the embattled country.
Mr Trump has yet to say how he intends to end this war, but allies are already blinking. In recent days, German Chancellor Olaf Scholz has spoken with Mr Putin for the first time in two years to the dismay of the Ukrainian president Volodymyr Zelenskyy, who described the call as “opening Pandora’s Box”.

Ukraine anger over Putin-Scholz call
Sir Keir for his part says he has “no plans’ to speak to Putin as the 1,000th day of this conflict comes into view. But as unity amongst allies in isolating Mr Putin appears to be fracturing, the Russian leader is emboldened: on Saturday night Moscow launched one of the largest air attacks on Ukraine yet.
All of this is a reminder of the massive implications, be it on trade or global conflicts, that a Trump White House will have, and the world will be watching to see how much ‘Trump proofing’ allies look to embark upon in the coming days in Rio, be that trying to strike up economic ties with countries such as China or offering more practical help for Ukraine.
Both Sir Keir Starmer and French President Emmanuel Macron want to use this summit to persuade Mr Biden to allow Mr Zelenskyy to fire Storm Shadow missiles deep into Russian territory, having failed to win this argument with the president during their meeting at the White House in mid-September. Starmer has previously said it should be up to Ukraine how it uses weapons supplied by allies, as long as it remains within international law and for the purposes of defence.
“I am going to make shoring up support for Ukraine top of my agenda as we go into the G20,” said Sir Keir when asked about pressing for the use of such weaponry.
“I think it’s important we double down and give Ukraine the support that it needs for as long as it needs it. Obviously, I’m not going to get into discussing capabilities. You wouldn’t expect me to do that.”

But even as allies try to persuade the outgoing president on one issue where consensus is breaking down, the prospect of the newcomer is creating other waves on climate change and taxation too. Argentine President Javier Milei, a close ally of Trump, is threatening to block a joint communique set to be endorsed by G20 leaders over opposition to the taxation of the super-rich, while consensus on climate finance is also struggling to find common ground, according to the Financial Times.

Where the prime minister has found common ground with Mr Trump is on their respective domestic priorities: economic growth and border control.
So you will be hearing a lot from the prime minister over the next couple of days about tie-ups and talks with big economic partners – be that China, Brazil or Indonesia – as Starmer pursues his growth agenda, and tackling small boats, with the government drawing up plans for a series of “Italian-style” deals with several countries in an attempt to stop 1000s of illegal migrants from making the journey to the UK.
Italy’s Prime Minister Giorgia Meloni has struck financial deals with Tunisia and Libya to get them to do more to stop small-boat crossings, with some success and now the UK is in talks with Kurdistan, semi-autonomous region in Iraq, Turkey and Vietnam over “cooperation and security deals” which No 10 hope to sign next year.
The prime minister refused on Sunday to comment on specific deals as he stressed that tackling the small boats crisis would come from a combination of going after the smuggling gangs, trying to “stop people leaving in the first place” and returning illegal migrants where possible.
“I don’t think this is an area where we should just do one thing. We have got to do everything that we can,” he said, stressing that the government had returned 9,400 people since coming into office.
But with the British economy’s rebound from recession slowing down sharply in the third quarter of the year, and small boat crossings already at a record 32,947, the Prime Minister has a hugely difficult task.
Team Trump: Who is in, and who is out?
Add the incoming Trump presidency into the mix and his challenges are likely to be greater still when it comes to crucial issues from Ukraine to climate change, and global trade. But what Trump has given him at least is greater clarity on what he needs to do to try to buck the political headwinds from the US to the continent, and win another term as a centre left incumbent.
The new trade tariffs announced by US President Donald Trump may place added pressure on the Bitcoin mining ecosystem both domestically and globally, according to one industry executive.
While the US is home to Bitcoin (BTC) mining manufacturing firms such as Auradine, it’s still “not possible to make the whole supply chain, including materials, US-based,” Kristian Csepcsar, chief marketing officer at BTC mining tech provider Braiins, told Cointelegraph.
On April 2, Trump announced sweeping tariffs, imposing a 10% tariff on all countries that export to the US and introducing “reciprocal” levies targeting America’s key trading partners.
Community members have debated the potential effects of the tariffs on Bitcoin, with some saying their impact has been overstated, while others see them as a significant threat.
Tariffs compound existing mining challenges
Csepcsar said the mining industry is already experiencing tough times, pointing to key indicators like the BTC hashprice.
Hashprice — a measure of a miner’s daily revenue per unit of hash power spent to mine BTC blocks — has been on the decline since 2022 and dropped to all-time lows of $50 for the first time in 2024.
According to data from Bitbo, the BTC hashprice was still hovering around all-time low levels of $53 on March 30.

“Hashprice is the key metric miners follow to understand their bottom line. It is how many dollars one terahash makes a day. A key profitability metric, and it is at all-time lows, ever,” Csepcsar said.
He added that mining equipment tariffs were already increasing under the Biden administration in 2024, and cited comments from Summer Meng, general manager at Chinese crypto mining supplier Bitmars.

“But they keep getting stricter under Trump,” Csepcsar added, referring to companies such as the China-based Bitmain — the world’s largest ASIC manufacturer — which is subject to the new tariffs.
Trump’s latest measures include a 34% additional tariff on top of an existing 20% levy for Chinese mining imports. In response, China reportedly imposed its own retaliatory tariffs on April 4.
BTC mining firms to “lose in the short term”
Csepcsar also noted that cutting-edge chips for crypto mining are currently massively produced in countries like Taiwan and South Korea, which were hit by new 32% and 25% tariffs, respectively.
“It will take a decade for the US to catch up with cutting-edge chip manufacturing. So again, companies, including American ones, lose in the short term,” he said.

Csepcsar also observed that some countries in the Commonwealth of Independent States region, including Russia and Kazakhstan, have been beefing up mining efforts and could potentially overtake the US in hashrate dominance.

“If we continue to see trade war, these regions with low tariffs and more favorable mining conditions can see a major boom,” Csepcsar warned.
As the newly announced tariffs potentially hurt Bitcoin mining both globally and in the US, it may become more difficult for Trump to keep his promise of making the US the global mining leader.
Trump’s stance on crypto has shifted multiple times over the years. As his administration embraces a more pro-crypto agenda, it remains to be seen how the latest economic policies will impact his long-term strategy for digital assets.

Cryptocurrency exchange OKX is under renewed regulatory scrutiny in Europe after Maltese authorities issued a major fine for violations of Anti-Money Laundering (AML) laws.
Malta’s Financial Intelligence Analysis Unit (FIAU) fined Okcoin Europe — OKX’s Europe-based subsidiary — 1.1 million euros ($1.2 million) after detecting multiple AML failures on the platform in the past, the authority announced on April 3.
While admitting that OKX has significantly improved its AML policies in the past 18 months, the authority “could not ignore” its past compliance failures from 2023, “some of which were deemed to be serious and systematic,” the FIAU notice said.
OKX was among the first crypto exchanges to receive a license under Europe’s new Markets in Crypto-Assets (MiCA) regulation via its Malta hub in January 2025.
The news of the $1.2 million penalty in Malta came after Bloomberg in March reported that European Union regulators were probing OKX for laundering $100 million in funds from the Bybit hack.
Bybit CEO Ben Zhou previously claimed that OKX’s Web3 proxy allowed hackers to launder about $100 million, or 40,233 Ether (ETH), from the $1.5 billion hack that occurred in February.
This is a developing story, and further information will be added as it becomes available.

Authorities in the US state of Massachusetts continue targeting unlawful cryptocurrency market practices, with a local court fining crypto financial services firm CLS Global.
A federal court in Boston on April 2 sentenced CLS Global on criminal charges related to fraudulent manipulation of crypto trading volume, according to an announcement from the Massachusetts US Attorney’s Office.
In addition to a $428,059 fine, the court prohibited CLS Global from offering services in the US for a probation period of three years.
CLS Global, a crypto market maker registered in the United Arab Emirates, in January pleaded guilty to one count of conspiracy to commit market manipulation and one count of wire fraud.
CLS agreed to manipulate the FBI’s “trap token” NexFundAI
The charges against CLS Global followed an undercover law enforcement operation involving NexFundAI, a token created by the FBI as part of a sting operation in May 2024.
CLS Global was among at least three firms that took the FBI’s bait and agreed to provide “market maker services” for NexFundAI, including a fraudulent scheme to attract investors to purchase the token.
In October 2024, the Securities and Exchange Commission announced fraud charges against CLS and its employee, Andrey Zhorzhes. The US securities regulator also filed complaints against two other NexFundAI manipulators, Hong Kong-linked ZM Quant Investment and Russia-linked Gotbit Consulting.
CLS Global’s profile
According to CLS Global CEO Filipp Veselov, the company was founded in 2017 to fill in a “huge gap in the market for high-quality market-making solutions and trading consulting.”
Prior to CLS, Veselov worked at the Russian cryptocurrency exchange platform Latoken, which is advertised as a “global digital asset exchange” and has about 370,000 followers on X.
The CLS team also includes chief revenue officer Pavel Singaevskii, who previously served as sales manager at Stex, a crypto platform that reportedly ceased operations without warning in 2023.

According to CLS Global’s X page, the platform continues operating and has more than 110,000 followers at the time of publication.
How much wash trading is in crypto?
Wash trading is an illegal practice involving artificially inflating trading volume by repeatedly buying and selling the same asset, generating a misleading perception of demand.
According to a January 2025 report by the US blockchain analytics firm Chainalysis, the crypto market has at least $2.6 billion in estimated wash traded volumes, or just about 2% of total daily crypto trading volumes, as reported by CoinGecko.

Some studies indicate that wash trading makes up a bigger share of the crypto market.
In 2022, the US National Bureau of Economic Research reported that illegal wash trading may account for as much as 70% of average trading volumes on unregulated exchanges.
