US President Donald Trump is now using alternative legal routes to levy tariffs, but critics say his authority to impose them is still limited.

United States President Donald Trump announced on Saturday that he is raising the 10% global tariff rate announced on Friday to 15%, which will take effect immediately. 
Trump reiterated his criticism of the Supreme Court’s decision to strike down his authority to levy tariffsunder the International Emergency Economic Powers Act (IEEPA). In a Saturday Truth Social post, he said:
“As President of the United States of America, I will be, effective immediately, raising the 10% worldwide tariff on countries, many of which have been ‘ripping’ the US off for decades, without retribution, until I came along, to the fully allowed, and legally tested, 15% level.”
On Friday, Trump announced a 10% global tariff rate to be added on top of already existing tariffs that remained valid after the court ruling, under alternative legal statutes outlined in the Trade Expansion Act of 1962 and the Trade Act of 1974. 

However, pro-crypto attorney Adam Cochran said the scope of these laws also limits Trump’s authority to levy broad tariffs indefinitely.
“The law he is using only allows this to be on countries we have a deficit with, for a set period of 150 days, and at a capped percentage,” he said. 
Each new tariff announcement from Trump caused turmoil in the crypto and stock markets, with severe downturns that negatively impacted asset prices and fueled macroeconomic uncertainty among investors.  
Crypto markets held firm in the wake of the latest tariff announcements
The crypto market, which usually experiences heavy sell-offs in response to tariff announcements, held firm in the wake of the latest tariff headlines.
The price of Bitcoin held steady at the $68,000 level, and Ethereum also remained firm, showing little to no change since Friday when the new tariffs were announced.
The Total3 indicator, which tracks the entire market capitalization of the crypto sector, excluding BTC and ETH, fell by less than 1% on Saturday and remains at about $713 billion at the time of this writing.

Johann Kerbrat, pointed out that crypto investors are looking for more ways to explore crypto beyond just holding tokens amid market uncertainty.

Crypto investors are increasingly exploring beyond the top three cryptocurrencies as the market downturn continues, according to Robinhood's head of crypto, Johann Kerbrat.
“I think what we see from our customers is that they actually see it as an opportunity,” Kerbrat told Cointelegraph during an exclusive interview, adding that they are seeing it as “an opportunity to buy the dip.”
“So we actually see a lot of customers continuing to trade crypto and diversifying, not just on the top two or three assets, but actually going pretty wide,” he said, referring to the largest two cryptocurrencies by market capitalization, Bitcoin and Ethereum.

It signals that investors are potentially becoming more comfortable with crypto as an asset class, including its volatility and market swings.
Investors have a “very clear view” on Bitcoin and Ethereum
It comes just months after Coinbase Asset Management president Anthony Bassili told Cointelegraph in November that the average investor still hasn’t reached a clear consensus on what the third crypto asset beyond the top two warrants serious attention. 
“The market is very unsure as to what’s the next asset they want to own after that,” he said, adding that Solana is “maybe” the third asset on the radar. Bassili said at the time that there is a “very, very clear view” in thecommunity in terms of Bitcoinbeing the first priority, followed by Ethereum.
Institutional crypto asset trading platform MidChains CEO Basil Al Askari told Cointelegraph that “we're seeing full-scale asset managers entering with very large block trades going into predominantly the top 20 assets.”
“Not necessarily smaller cap altcoins, or not necessarily into DeFi or yield products,” Al Askari said, adding, “it's baby steps.”
“I don't think it's impossible to see large investment managers and funds build specific teams around strategies that do different things along the risk curve, and so I do think that's very possible,” Al Askari said.
Crypto holders are looking for use cases
Meanwhile, Kerbrat said he’s also seeing more crypto holders on the platform not just holding their tokens, but actively using them.
Kerbrat said staking has gained “very strong traction” since Robinhood rolled out the feature in December, and that more crypto holders are now exploring decentralized finance (DeFi) despite the market uncertainty.
“It’s been pretty fun to see, to be honest. It's always surprising,” Kerbrat said. 
It comes as overall crypto sentiment has weakened, with the Crypto Fear & Greed Index remaining in “Extreme Fear” since the start of February.
Meanwhile, US spot Bitcoin exchange-traded funds (ETFs) have posted five consecutive weeks of net outflows, with investors pulling roughly $3.8 billion from the products over the period.

Trump mengeluarkan pernyataan, keputusan Mahkamah Agung AS kemarin tentang tarif adalah tidak masuk akal dan buruk, saya ingin menyatakan bahwa, sebagai Presiden Amerika Serikat, saya akan segera meningkatkan tarif global 10% yang diterapkan pada banyak negara menjadi 15% sepenuhnya legal dan telah diverifikasi secara hukum.
Banyak negara di antara ini telah "mengepung" Amerika selama beberapa dekade tanpa mendapatkan hukuman apa pun. Dalam beberapa bulan mendatang, pemerintahan Trump akan menentukan dan mengumumkan tarif legal baru, yang akan melanjutkan proses luar biasa untuk membuat Amerika hebat kembali - lebih hebat dari sebelumnya!

Di ETH Denver, para pengembang memperingatkan bahwa kemajuan dalam komputasi kuantum dapat mengancam tanda tangan digital Bitcoin ketika industri terus memperdebatkan bagaimana mempersiapkan diri.

Sementara konferensi pengembang Ethereum tahun ini, ETH Denver, fokus pada pembangunan di pasar yang menurun dan memberdayakan agen AI melalui blockchain, satu panel mengkaji apakah kriptografi Bitcoin dapat bertahan di dunia pasca-kuantum.
Di atas panggung minggu ini, fokus pada kemampuan Bitcoin untuk bertahan dari ancaman komputasi kuantum sangat sempit, berfokus pada apa yang sebenarnya bisa rusak lebih dulu. Menurut Hunter Beast, penulis bersama BIP 360—sebuah proposal yang bertujuan untuk menyelesaikan teka-teki kuantum blockchain—kebingungan sering dimulai dengan algoritma hashing Bitcoin.
