Nobel Prize-winning physicist John Martinis warns Bitcoin (CRYPTO: BTC) could be cracked in minutes by quantum computers but says the community has 5-10 years to upgrade to quantum-resistant encryption.

The Minutes Warning

A recent Google paper endorsed by Martinis shows how a sufficiently advanced quantum computer could derive a Bitcoin private key from its public key in minutes, exploiting the brief window when a transaction’s public key is exposed before confirmation.

The vulnerability centers on a specific exposure window. 

When a Bitcoin transaction is broadcast, its public key becomes visible before it is confirmed on-chain. 

A powerful quantum computer could use that window to…

Bitcoin (CRYPTO: BTC) has been trading below $70,000 for nearly two weeks, moving sideways and testing traders’ patience.

Despite this consolidation, several on-chain metrics are signaling underlying strength.

Network Activity Jumps

Data from CryptoQuant shows a sharp increase in network activity after months of decline.

The Network Activity Index has rebounded alongside key metrics such as active addresses, transactions, UTXOs, and block space demand.

Daily transactions have risen to around 615,000, the highest level since November 2024, indicating stronger on-chain engagement and increased usage of the network.

This surge is happening in a low-fee environment, which is significant.

XRP (CRYPTO: XRP) has surged about 163% since the November 2022 FTX collapse, but this headline growth masks a much weaker reality for most investors.

XRP’s Wallet Holders

Despite the price increase, data from Santiment shows that active XRP wallets are sitting on average losses of around 41%, meaning a large share of holders bought at higher prices and are still underwater.

This is reinforced by the MVRV ratio dropping to its lowest level since the FTX crash, a signal that most investors are holding at a loss.

Further on-chain insights from Glassnode indicate that more than half of XRP’s circulating supply is currently underwater, largely due to heavy accumulation above the $2 level over…

Altcoin markets remain under heavy pressure, with many assets down 70–80%, but recent data shows a notable shift in where trading activity is flowing.

Trader Behavior Shift

According to data from CryptoQuant, altcoin inflows spiked to around 34,000 on Apr. 2, the highest in 2.5–3 months, but unusually, this surge was concentrated almost entirely on Binance rather than spread across multiple exchanges.

This concentration suggests a shift in trader behavior.

One key reason is Binance’s expansion into traditional finance (TradFi) futures, including contracts tied to commodities like oil, natural gas, gold, and silver.

As trading volume in these assets increases, it appears that some…

The Q1 Loss

Strategy held more than $50 billion of cryptocurrency at quarter-end as Bitcoin tumbled more than 20% in Q1, the largest first-quarter drop since 2018.

The company adopted accounting standards last year requiring changes in Bitcoin holdings to flow through earnings, driving multibillion-dollar swings in results. 

Strategy reported a $2.42 billion deferred tax benefit in the quarter.

Strategy bought 4,871 Bitcoin from April 1-5 for $330 million at an average price of $67,700, funded through Class A common stock sales and Stretch preferred share sales.

The company has $2.25 billion in cash reserves, enough to cover interest and distributions for more than two years.

Ripple is expanding into Africa’s $205 billion crypto market with RLUSD partnerships and custody solutions as XRP (CRYPTO: XRP) tests the $1.30 support that has held multiple times over the past two weeks.

The Africa Push

Sub-Saharan Africa received more than $205 billion in on-chain value between July 2024 and June 2025, a 52% year-over-year increase. 

Nigeria ranked 6th and Ethiopia 12th in the 2025 Global Crypto Adoption Index.

Ripple’s RLUSD stablecoin has seen strong demand across Africa through partnerships with Mercy Corps Ventures in Kenya for aid delivery, plus Chipper Cash, VALR, and Yellow Card for institutional access. 

Moreover, Absa Bank signed a strategic partnership for…
