GPU-friendly algorithms, like Ethash or Autolykos, make answering what crypto can be mined easier for small-scale miners with standard GPUs. These algorithms favor accessibility, but rising difficulty can choke returns. Experience shows GPU-friendly coins yielding 30% monthly profits, while high-difficulty spikes cut 20%. You must track algorithm difficulty, coin rewards, and social media sentiment. A low-difficulty algorithm could earn $250 monthly on a $1,500 GPU rig; a tough one might scrape $50. Hit the sweet spot, or you’re grinding for pennies.
