Crypto this week (24–30 Aug 2026): five common crypto myths checked against the facts

After a sharp rise the week before, the week of 24 to 30 August 2026 was almost flat: bitcoin ended just 0.1% lower in dollars. Quiet weeks are a good moment to test a few things people new to crypto often hear. We took five common beliefs and checked each one against what actually happened this week, using verified sources only.

Key points: what happened in crypto this week?

• Bitcoin ended the week at $77,668 (€67,012): 0.1% lower in dollars but 0.7% higher in euros, because the euro weakened against the dollar.
• On 28 August bitcoin fell below $78,000 on the day of a speech by the US Federal Reserve chair, which CoinDesk linked to the move.
• Cronos halted its whole blockchain after an estimated $75 million exploit of a lending app built on it.
• Revolut began offering EURR, a euro stablecoin, to selected customers in Denmark, Poland and Portugal.
• US spot bitcoin ETFs took in $924.5 million, even though the price barely moved.

Myth 1: "Bitcoin moves on its own, whatever central banks do"

On Friday 28 August, Kevin Warsh, chair of the Federal Reserve (the US central bank), gave his first speech as chair at Jackson Hole, a yearly meeting of central bankers. In the speech he said inflation is above the Fed's 2% target, with 12-month PCE inflation (a price measure the Fed watches) at 3.7%, and that "the Fed's predominant focus right now should be on prices".

CoinDesk reported that bitcoin "headed lower on the hawkish remarks". "Hawkish" means leaning towards higher interest rates. Bitcoin fell below $78,000 and was down 3.2% over 24 hours by 12:11 New York time. Traders raised the odds of a US rate rise in September to about 60%, from about 35% a day earlier, CoinDesk reported.

But the speech was not the whole story. Bitcoin had already slipped from its overnight high of about $81,000 to just above $79,000 before Warsh spoke, as markets turned cautious ahead of the speech, CoinDesk reported. The week's high, $81,347 (€69,808), came in the early hours of that same day. Over the full week, bitcoin went from $77,749 to $77,668, and ether ended 1.9% lower at $2,418.

So: bitcoin does react to central banks: one speech moved it within a day. But this one came on top of a fall that had already started, and the week as a whole ended almost flat.

Myth 2: "A stablecoin is a coin that simply can't lose value"

A stablecoin is a crypto token designed to keep a steady value against a currency, here the euro. On Wednesday 26 August, Revolut began a phased rollout of EURR, a stablecoin meant to be worth €1, to "a select group of customers" in Denmark, Poland and Portugal, with wider availability across the European Economic Area planned later.

What stands behind the €1? Revolut's EURR is legally issued by Bridge (Bridge Building S.A., owned by Stripe), which CoinDesk says is authorised as an electronic money institution and supervised in Luxembourg. The token can be redeemed at €1. When CoinDesk published, Bridge's reserve page showed just 374 EURR in circulation, backed by €374 in cash deposits.

Under MiCA, the EU's crypto rulebook, a euro stablecoin is an e-money token, which only an authorised bank or e-money institution may issue. One detail to watch: another euro stablecoin, from StablR, uses the same EURR ticker, so check the issuer, not just the name. Euro stablecoins are still small: under $800 million in total, against a stablecoin market of over $300 billion (DefiLlama data cited by CoinDesk). Our stablecoins course explains the basics.

So: a stablecoin is designed to hold its value, and what supports that design is its issuer and its reserves. It can still lose its peg: in March 2023 the dollar stablecoin USDC fell as low as $0.88 after its issuer disclosed that part of its reserves was held at the failed Silicon Valley Bank, Reuters reported.

One EU date to get right: some pages still gave 31 August as the closing date of the European Commission's consultation on reviewing MiCA. It did not close then: on 29 June the Commission had extended the deadline to 30 September 2026. ESMA, the EU's markets supervisor, published nothing crypto-specific this week.

Myth 3: "A blockchain can't be paused"

On Sunday 30 August, Cronos halted its entire blockchain. The trigger was an exploit of Tectonic, a lending app on Cronos. A lending app lets people borrow crypto by depositing other crypto as collateral, a deposit that secures the loan.

According to CoinDesk, the alleged method was this: an attacker pushed up the price of TONIC, Tectonic's own thinly traded token (one with few buyers and sellers), about 100-fold in about 20 minutes. They then deposited it as collateral and borrowed real assets against it. On-chain researcher Weilin Li estimated the losses at about $75 million, and security firm PeckShield at about $74 million. Neither Cronos nor Tectonic had confirmed a figure as of Monday morning. Li estimated that about $6 million was moved to Ethereum before the halt. The value of everything deposited in Tectonic fell from about $121.7 million on 26 August to about $3 million. Cronos later said the chain was producing blocks again, with its state restored to before the exploit. Our introduction to security covers the basics.

So: some blockchains can be paused, and while a chain is halted, everyone's funds on it are stuck, not only the victims'.

Myth 4: "If money flows into crypto funds, prices must be rising"

An ETF (exchange-traded fund) is a fund that trades on a stock exchange like a share; a "spot" bitcoin ETF holds actual bitcoin. This week, US spot bitcoin ETFs took in $924.5 million in total. Monday alone brought $337.56 million. Their run of inflows reached nine trading days before a $201.9 million outflow on Friday, the day of the Warsh speech. BlackRock's IBIT alone took in about $938.3 million, so the other funds together had net outflows. US spot ether ETFs took in about $820 million, depending on the tracker.

Meanwhile, bitcoin ended the week 0.1% lower in dollars and ether 1.9% lower. Our investment basics course explains what fund flows are.

So: fund flows and prices measure different things, and a week can bring large inflows and a flat price at the same time.

Myth 5: "A famous sponsor means a crypto firm is safe"

Zondacrypto, a crypto firm, sponsored the Polish Olympic team. In April 2026 its customers reported that they could not access their funds. The firm collapsed and its former head went into hiding abroad, Notes from Poland reported.

On Thursday 27 August, Poland's Justice Minister and Prosecutor General, Waldemar Żurek, announced that Radosław Piesiewicz, president of the Polish Olympic Committee, had been detained in the criminal investigation into Zondacrypto. Prosecutors are investigating suspected large-scale fraud and estimate client losses of at least PLN 350 million (about €81.4 million). Piesiewicz denies wrongdoing. Our spot-the-scam course shows more warning signs to look for.

So: a sponsorship or a famous name is not a safety check. Whether a provider is authorised, for example in ESMA's MiCA register, is something you can check before depositing. Authorisation is not a guarantee either, but it tells you which authority supervises the firm.

What to take from this week

Each of these beliefs sounds reasonable, and each met a fact this week that complicates it. A speech moved bitcoin within a day, yet the week ended flat. A stablecoin's €1 depends on who issues it and what backs it. A blockchain was switched off. Money flowed into funds while prices stood still. And a famous sponsorship was no guarantee: the firm behind it collapsed. Checking the source behind a claim is usually more useful than the claim itself.

• Learn why interest rates and central-bank speeches can move crypto prices in about the crypto market.
• Find out what MiCA means for stablecoins and crypto firms in crypto rules in the EU.
• Pick one belief you hold about crypto and look for a primary source, such as a regulator or central bank, that confirms or challenges it.
