Samsung makes a mobile mining rig
This news is becoming old, but still worth mentioning: Samsung, the technological giant and one of the most serious rivals of Apple, plans to redefine the use of its old products by turning them into mining apparatus. This picture made by Kyle Wiens went viral due to the highly atypical appearance of the mining rig:
Forty units of Galaxy S5 are used, and while this rig, resembling the Chinese pagoda, still cannot compete with vast mining farms in China, it can become an opportunity for someone not willing enough to buy and combine video chips. No information regarding this system durability is also present, but one can guess that if mining forums advise not to use laptops for mining, mining will not make mobile devices any better. This, by the way, is why old devices are used.
We might see the issue of special mobile devices designed specifically for mining once someone on the market recognizes this concept as a business opportunity. This already happened to motherboards, with ASUS issuing its B250 Mining Expert with 19 expansions slots (even though at the time, both Nvidia and AMD GPU drivers supported only up to 8 combined GPUs).
