Crypto has gone bananas

For years, GPU mining was the backbone of many cryptocurrencies, especially Ethereum. Graphics cards offered flexibility: miners could switch between coins depending on profitability, and the barrier to entry was relatively low. This accessibility helped fuel a global wave of small-scale, home-based mining operations.

However, the landscape began to shift dramatically. The most significant turning point came with Ethereum Merge, when Ethereum moved from proof-of-work (mining) to proof-of-stake. This effectively eliminated one of the most profitable GPU mining opportunities overnight. As a result, countless GPUs flooded secondary markets, and mining profitability for remaining GPU-mineable coins dropped sharply due to oversaturation.

At the same time, ASIC (Application-Specific Integrated Circuit) mining had already been on the rise. Unlike GPUs, ASICs are purpose-built machines designed to mine specific algorithms with extreme efficiency. Cryptocurrencies like Bitcoin have long relied on ASIC miners, making GPU mining obsolete in that ecosystem. Companies such as Bitmain drove this shift by producing increasingly powerful and specialized hardware.

Initially, ASICs represented a leap forward in mining performance and profitability. But this evolution came with trade-offs—especially for private individuals. The cost of entry skyrocketed, with high-end ASIC units costing thousands of dollars, often coupled with significant electricity demands. Large-scale mining farms, often located in regions with cheap power, began to dominate the network hashrate.

Today, ASIC mining is facing its own form of “downfall” for small players. Increased competition, rising energy costs, and periodic market downturns have squeezed profit margins. Additionally, mining difficulty continues to climb, meaning individual miners earn less over time unless they continuously reinvest in newer hardware. For many private users, the economics no longer make sense.

In effect, crypto mining has shifted from a decentralized hobbyist activity to a capital-intensive industrial operation. GPU mining has largely faded as a viable income source, and while ASICs still power major networks, they have also contributed to centralization—making it increasingly difficult for individuals to compete.
