The Garmin Venu 4 is a great Garmin watch, but it doesn't necessarily look like a Garmin. Most people think of the lumpy black Fenix, Forerunner, and Instinct ranges, but the Venu series has always been a bit sleeker, just at home in the office as it is on the trail or in the gym.

Consequently, I labeled it my 'best Garmin watch for most people' when I reviewed it in October last year, and that remains my opinion due to its status as the ideal all-rounder watch: enough features to satisfy everyone but die-hard trail enthusiasts and orienteers, and an understated look ideal for modern life. It was my opinion when the watch was full price, and it's definitely still my opinion now that it's hit a lowest-ever price during the Amazon Prime Day sales.

Are you after something a little cheaper? The Garmin Vivoactive 5 is a similar all-rounder fitness tracker, albeit less premium and older than the Garmin Venu 4. Where the Venu uses metal, the Vivoactive uses plastic, and the Vivoactive uses an older heart rate sensor. It misses out on a few key smartwatch features such as the voice assistant and some more advanced workout metrics. However, it's currently very affordable and is a great budget alternative.

The Garmin Vivoactive 5 is a fantastic all-rounder fitness smartwatch with tonnes of workout plans, a crisp AMOLED display, onboard GPS, and 11 days of battery life. At this price, you'll be hard-pressed to find a better-performing watch for general fitness, health, and exercise tracking.View Deal

A lowest-ever price on the Garmin Vivoactive 5 means there's never been a better time to snap this up. Garmin's comprehensive and (still mostly free) app has served me well for years, while the Vivoactive 5 at this price is an easly swallow for Fitbit users used to cheaper devices. View Deal

• AiOnX takes 77% share in US-based cryptocurrency miner
• The deal sees it take control of 15 data centers in the US and Sweden
• The $500 million acquisition sees it secure access to 1.3 Gigawatts of power, an increasingly scarce commodity for AI datacenters

AiOnX, a major data center infrastructure developer focused on hyperscalers across Europe, has taken a majority stake in the US-based cryptocurrency mining firm Genesis Digital Assets.

The transaction, valued at $500 million, sees its parent company, SWI Group, take a 77% stake in GDA, and gives it control over 15 cryptomining data centers across the US and Sweden - and perhaps more importantly, access to 1.3 Gigawatts of available power.

The agreement encompassing 15 data centers across North Carolina, South Carolina, and Texas, as well as two sites in Sweden.

The move by SWI Group was reported by DataCenterDynamics, which said a deal was in the works between SWI and a then-unnamed US cryptomining entity.

It seems to have been dictated by GDA's access to readily available power, even as most hyperscaler buildouts continue to struggle with their own power limitations, and as studies indicate it could eventually stall AI datacenter growth by as early as 2030.

The reason for GDA making for a relatively no-brainer acquisition by SWI, thanks to its power connectivity.

"Power connectivity is the most valuable commodity in digital infrastructure today, and converting legacy cryptocurrency mining infrastructure to AI and high-performance computing is the best and highest use of these assets," noted SWI founder and CEO, Max-Hervé George.

"We have been investing in power-connectivity since 2020. This is what that thesis looks like at scale."

This is not an isolated move, however, with many cryptocurrency miners now pivoting to or getting outright acquired by AI hyperscalers as demand for compute, and, in tandem, power continues unabated as models get larger over time.

The reason is that not only is cryptomining relatively unprofitable compared to AI workloads that rent out GPUs under long-term contracts, but it is also inconsistent, given that cryptocurrency prices tend to fluctuate, making for an unpredictable payday for cryptominers, many of whom are heavily infused with debt to cover their scaling needs.

While modern crypto ASICs can not be repurposed for AI needs, the power they consume, much of which is locked in via long-term contracts, is much more valuable for AI datacenters since their power needs are already taken care of and available on-site, versus many otherwise ambitious and time-consuming power generation projects that some hyperscalers have directly been forced to invest in.

For context, as per estimates by Coindesk, AI contracts offer margins of as much as 85% with multi-year revenue visibility in tow, making cryptomining, even as hashrates continue to climb, while Bitcoin remains below $70,000, reflecting a broader crypto market that some feel has already entered a bear-induced winter.
