Cold Wallet Vulnerability Alert: Upgrade Firmware—Upgrading Doesn’t Automatically Make Old Seeds Safe

First, the most important: if you have used an affected version of Coldcard, don’t stop at just updating the firmware. The official fix applies to the path used for generating future seeds; seeds that were already generated on older versions will not become automatically secure after an upgrade.

For practical checking, look at your version: Mk2/Mk3 need to be updated to 4.2.0+; Mk4/Mk5 standard to 5.6.0+; Edge to 6.6.0X+. Q standard to 1.5.0Q+; Edge to 6.6.0QX+. Then, on the patched firmware, generate completely new seeds again. Verify the wallet fingerprint and the receiving address. Start with a small test transaction, confirm it has arrived, and only then migrate balances. Keep the old backup for now. The BIP-39 passphrase must be stored separately from the mnemonic, and a PIN cannot replace it.

After the 2021 code migration, some firmware routed rng_get() to the MicroPython software PRNG instead of the expected hardware RNG, resulting in insufficient entropy for certain seeds. CoinDesk, citing researchers, said that after July 30, at least 1,816 BTC—drawn from 5,200+ addresses—was taken. Snapshot figures from other reports differed, and the scale of losses depends on the statistical methodology used. For $BTC , what’s worth remembering is this: offline, open-source, and verifiable are not a single-point guarantee of security. Custodial or spot ETFs may absorb some demand, but they simply shift device risk to counterparties—along with regulatory, fee, and withdrawal risks.

Don’t treat the $473 million lawsuit amount as a fait accompli yet.

First, remember this key judgment: Binance-related entities have sued Hong Kong stablecoin payment company RedotPay and its founder. They allege that RedotPay diverted nearly 470,000 Binance customers and claim losses of nearly $473 million. But these are the plaintiffs’ allegations in the lawsuit, not outcomes that the court has already determined.

The core of the dispute isn’t just the compensation amount. It also concerns whether Binance Pay funds were segregated, whether they can be used for restricted purposes, and whether they were used to top up the RedotPay card. RedotPay’s website states that this process will not affect day-to-day operations now or in the future, and it says it will actively defend against all allegations.

I think what ordinary users should most save is this order of judgment: first review the complaint and the contract, then see whether the court has issued a temporary injunction, and only then look at the substantive ruling. Before using a crypto payment card, you should also confirm the card-issuing entity, the custody and segregation arrangements for funds, the permitted top-up routes, the freeze rules, and how disputes are handled.

According to search results on Singapore’s judiciary website, the related case HC/OC 430/2026 will hold a procedural Case Conference on August 7, 2026. Its lesson for the market is that reliance on channels among exchanges, stablecoin payment providers, and crypto cards can turn cooperation terms directly into operational risk. For $BTC , $ETH , and $BNB , this is more like an observation point on payment infrastructure and compliance boundaries—not a buy/sell signal driven by price movements of a single coin.

Encryption political donations lost a round—doesn’t mean the industry has lost influence

First, the conclusion: this looks more like a stress test of political funding efficiency for the crypto industry, not evidence that “the industry lost in the U.S.”

CBS News reported that in Michigan’s 13th congressional district Democratic primary, Donavan McKinney defeated incumbent Shri Thanedar. CoinDesk said Fairshake spent more than $2 million on campaigns related to Thanedar, yet that same night, most of the other candidates it backed won.

Overall performance: a Super PAC can buy ads and visibility, but it can’t replace local grassroots foundations, candidate branding, or on-the-ground mobilization. Going forward, when you see “a PAC invested millions,” it’s a good idea to first check the FEC committee type and the independent expenditure records—especially since the spending is tied to advertising.

Next, focus on the PAC’s overall win rate, key committee seats, and whether these candidates can win the November general election. To judge whether legislators truly support crypto, don’t rely only on labels—look further at bill co-sponsorship, committee votes, and the final floor vote.

Before allocating BTC, ask yourself how much drawdown you can tolerate

“How much to allocate, and how to hold it.” This CoinDesk backtest uses a traditional 60/40 portfolio as the baseline, adds spot BTC at 2.5% and 10%, rebalanced monthly, and covers the period from January 2021 to March 2026.

The results are straightforward: the higher the BTC weight, the better the portfolio’s returns and Sharpe ratio in strong years—but volatility and maximum drawdown are amplified at the same time. A small allocation can change overall portfolio performance, but it won’t turn it into an all-crypto portfolio. The trend rule switches between BTC and cash, with a relatively steadier path, but you have to trade some upside potential for better drawdown control.

In practice, it’s recommended to first set a maximum total portfolio drawdown you can accept, then work backward to determine the BTC position size. Next, test both spot-holding and trend-based strategies separately under bull, bear, and sideways market conditions. Don’t just focus on cumulative returns—include turnover, fees, slippage, and whether you can execute the plan consistently over the long run. Backtests can help you build a risk budget, but they can’t guarantee the outcome of the next cycle.

Seeing “Bought $BNB in 2017”—don’t rush to calculate getting rich

Seeing “Bought $BNB worth 1,000,000 RMB in 2017,” many people’s first reaction is: how much is it worth now? But this kind of content is the easiest way to treat emotion as evidence. The narrative usually contains only the year, the amount, and the cryptocurrency. There’s no specific purchase date, execution price, exchange rate, fees, valuation timestamp, or exit path. It’s more like a counterfactual daydream, not a trade record that you can actually reconstruct.

I personally start by making a verification checklist: the exact date, purchase price, the currency used for valuation, exchange rate, fees, position size, valuation timestamp, sell method, and taxes. Missing even one parameter can cause the result to be inflated by the highest price, an ideal exchange rate, or ignored costs. In practice, using data with a unified timestamp, you should at least list three scenarios: holding, selling in batches, and exiting at different time points.

When looking at historical returns, first ask: are the parameters complete, can the data be reconstructed, and has risk been accounted for? Put $BTC , $ETH , and other major coins in the same category—price volatility, liquidity, custody, platforms, and regulation can all change the final outcome. Treat “if that year” as the entry point for reconstruction, not as an implication of future returns.
