New bull cycle? Bitcoin's return to $100K hints at ‘significant price move’

Published

on

By

Key points:

Bitcoin’s realized cap is beating records and has almost reached the $900 billion mark.

The market is laying the foundations for a “potentially significant price breakout,” new analysis says.

Profit-taking is not hindering the overall bull market rebound.

Bitcoin (BTC) is setting new all-time highs in network value as BTC price action eyes a return to six figures.

Data from onchain analytics platform CryptoQuant confirms new record highs for Bitcoin’s realized cap.

Bitcoin realized cap reflects “growing conviction”

Bitcoin is worth more than ever in US dollar terms if its market cap is measured by the value at which the extant supply last moved onchain.

Known as realized cap, this figure has seen continued all-time highs since mid-April as BTC/USD stages a sustained recovery, and as of May 7 stood at $891 billion.

“Bitcoin has experienced a steady flow of capital inflows in recent weeks, reflecting renewed interest from investors,” CryptoQuant contributor Carmelo Alemán summarized in one of its “Quicktake” blog posts on May 7.

Alemán argued that the realized cap uptrend reflects a long-term market shift across the Bitcoin investor spectrum.

“This new all-time high in Realized Cap not only reflects a surge in invested capital but also a growing conviction in Bitcoin’s long-term potential as a financial asset,” the post concluded. 

“With sustained accumulation from both LTHs and STHs, the market appears to be building a solid foundation for a potentially significant price breakout. If this trend continues, we could be witnessing the early stages of a new bull cycle for Bitcoin.”Bitcoin realized cap. Source: CryptoQuant

BTC capital influx ongoing since 2023

As Cointelegraph reported, concerns remain over the fate of the current market rebound.

Misgivings over profit-taking in particular form grounds to suspect that higher prices may not last — both LTH and STH entities have seized the opportunity to lock in profits, with these averaging $1 billion daily.

In the latest edition of its regular newsletter, “The Week Onchain,” research firm Glassnode nonetheless argues that buy and sell-side conditions are balanced at around $100,000.

“A surge in profit taking can be observed in recent weeks, with the recent rally drawing in over $1B/day in net capital inflows,” it wrote. 

“This points to initial indicators of a return of demand-side strength, allowing sellers to lock in profits, and speaking to buyers willing to pick up coins at the current market price. Generally speaking, this points to a wave of demand which is absorbing the incoming supply.”Bitcoin net realized profit/loss (screenshot). Source: Glassnode

Glassnode added that the quest for profits has, in fact, extended for over 18 months.

“Notably, the market has sustained a profit-driven regime since October 2023, with capital inflows consistently exceeding outflows. This steady influx of fresh capital serves as an overall constructive signal,” it stated.

60K Bitcoin addresses leaked as LockBit ransomware gang gets hacked

Published

on

By

Almost 60,000 Bitcoin addresses tied to LockBit’s ransomware infrastructure were leaked after hackers breached the group’s dark web affiliate panel. 

The leak included a MySQL database dump shared publicly online. It contained crypto-related information that could help blockchain analysts trace the group’s illicit financial flows.

Ransomware is a type of malware used by malicious actors. It locks its target’s files or computer systems, making them inaccessible. The attackers typically demand a ransom payment, often in digital assets like Bitcoin (BTC), in exchange for a decryption key to unlock the files.

LockBit is one of the most notorious crypto ransomware groups. In February 2024, 10 countries launched a joint operation to disrupt the group, saying that the organization had caused billions in damages to key infrastructure.

No Bitcoin private keys leaked

While almost 60,000 Bitcoin wallets were leaked, no private keys were included. One X user shared a conversation with a LockBit operator, confirming the breach. However, the LockBit person said no private keys or data were lost. 

Despite this, analysts at Bleeping Computer said the database contained 20 tables, including a “builds” table. This included individual ransomware builds created by the organization’s affiliates. The data also identified some of the target companies for the builds. 

In addition, the leaked database also included a “chats” table. This table contained over 4,400 negotiation messages between victims and the ransomware organization.

LockBit hack tied to Everest ransomware breach

It’s unclear who was behind the breach and how they got into LockBit’s operations, but Bleeping Computer analysts said the message used in the Everest ransomware site breach matched the one used in LockBit. The analysts suggested that there may be a link between the two incidents. 

The breach highlighted the role that crypto plays in the ransomware economy. Each victim is usually assigned an address to pay their ransom, allowing the affiliates to monitor payments while attempting to obscure ties to their main wallets. 

The exposure of the addresses allows law enforcement and blockchain investigators to track patterns and potentially link past ransom payments to known wallets.

Can you mine Bitcoin with a gaming PC? Here’s what you need to know

Published

Is your gaming PC capable of mining crypto?

As of May 2025, Bitcoin mining is looking attractive again. With Bitcoin (BTC) trading around $95,000 and transaction fees hitting new highs after the 2024 halving, mining rewards — though smaller — are worth chasing. From home setups to industrial-scale farms, the question of whether Bitcoin mining is profitable is back in the spotlight.

And if you’re a gamer, chances are you’ve looked at your rig and wondered: Can a gaming PC mine crypto? After all, modern gaming computers are packed with powerful GPUs, solid cooling and lots of downtime, especially if you’re not gaming daily. It’s a fair question: Can you mine Bitcoin with a gaming PC?

The short answer: Yes, but it won’t be worth it. 

The long answer: 

Understanding Bitcoin mining

Mining is the process that adds new BTC to circulation. More importantly, it’s how the Bitcoin network stays secure and functions without a central authority. Every time someone sends or receives Bitcoin, miners verify and record that transaction.

This is all powered by proof-of-work (PoW), a consensus mechanism where miners race to encode transactions in a format that is acceptable to the network. It’s essentially just a massive guessing game, where miners try different inputs until one generates a hash with enough leading zeroes to meet the network’s current difficulty target.

For example, a valid Bitcoin block might start with something like 00000000000000000000956e9ff76455…. The first miner to hit that valid hash wins the reward: currently 3.125 BTC, plus transaction fees.

The issue is, to generate that many leading zeroes in 2025, you’re looking at around 10³¹ hash attempts on average to produce a valid hash.

As you can imagine, that takes a lot of power.

Did you know? The energy used to mine a single Bitcoin block today could power an average US household for over 10 years. That’s the cost of making sure the network stays decentralized and tamper-proof.

From CPUs to ASICs: How mining hardware evolved

It didn’t use to be this hard to mine Bitcoin. As more miners joined the network and the total computing power surged, the protocol automatically ramped up the difficulty. 

That’s by design. Bitcoin adjusts to keep block times steady at around 10 minutes, no matter how much horsepower is thrown at it.

Back in 2009, Bitcoin mining for beginners meant using a regular laptop CPU. Then came the rise of GPUs — graphics cards originally built for gaming — which dramatically improved mining performance.

But then came ASICs, application-specific integrated circuits, designed solely to mine Bitcoin. These machines are vastly more powerful and energy-efficient than any GPU. By 2015, they had effectively taken over the mining scene.

Fast forward to 2025: ASICs still reign supreme. If you’re wondering about the best setup for mining Bitcoin on PC, know that ASIC vs. GPU mining isn’t a fair fight anymore. That doesn’t mean your gaming rig is useless, but it does mean you’ll want to consider alternative strategies.

Gaming PCs vs. ASIC miners

Bitcoin mining with a gaming PC, even with a high-end GPU like the RTX 4090, is inefficient and unlikely to be profitable due to low performance, high energy costs and hardware wear-and-tear compared to ASIC miners.

Performance: Can your GPU keep up?

Let’s say you’re using an Nvidia GeForce RTX 4090 — top of the line. Sounds heavy-duty, right?

Not for Bitcoin GPU mining.

That card might do well on other algorithms like Ethash (used in Ethereum Classic), but when it comes to Bitcoin’s SHA-256, it barely scratches the surface. Even the mighty RTX 4090 gets crushed by ASICs. A high-end ASIC like the Antminer S21 Pro pumps out 200 terahashes per second (TH/s) — that’s trillions of hashes per second, compared to maybe a few hundred megahashes per second from a GPU. That’s a millionfold difference.

Efficiency: The electricity bill tells the real story

Let’s talk about power. A GPU like the 4090 pulls around 450 watts. But the hashing performance it delivers is minuscule compared to the watts consumed. ASICs, by contrast, draw more power (e.g., 3,500 watts) but deliver far better output — roughly 17.5 joules per terahash.

In short, even if you’re mining Bitcoin on a gaming PC 24/7, the energy cost per dollar earned is painful. Is Bitcoin mining profitable with a gaming PC? Not really. Especially when you factor in cooling, hardware strain and your local energy prices.

Economics: Does it make any sense?

Even with low electricity rates, the ROI on mining Bitcoin from home with a gaming computer is near zero — if not outright negative. Solo mining? Forget it. The chances of hitting a block are microscopic. Pool mining? Your contribution is so small compared to ASIC farms that the payouts will be negligible.

And then there’s the wear and tear. GPUs weren’t designed to run at full capacity around the clock. Long-term mining can shorten their lifespan and may void warranties.

Alternative cryptocurrencies for gaming PCs

If Bitcoin mining on PC feels like bringing a Nerf gun to a tank fight, don’t lose hope. There are still coins designed to be mined with GPUs in 2025 — and some even reward users fairly for it.

Let’s take a look at such cryptocurrencies:

Ethereum Classic (ETC): GPU-friendly legacy chain

Still using the Ethash algorithm, Ethereum Classic (ETC) is a solid option for GPU miners. Blocks are mined every 13 seconds with a 3.2 ETC reward. 

Ravencoin (RVN): Built for the people

Ravencoin uses KAWPOW, an algorithm specifically designed to resist ASIC domination. It’s friendly to GPU miners and offers quick one-minute blocks with 2,500 Ravencoin (RVN) rewards. Mining altcoins with GPU setups is still very viable here.

Monero (XMR): Privacy-first and CPU/GPU accessible

Monero relies on the RandomX algorithm, making it accessible to both CPU and GPU miners. You won’t get rich, but it’s a way to earn passively, especially if you’ve got cheap electricity and want passive income from mining.
