With rates above \u20ac0.12\/kWh, electricity absorbs the profit. It only pays off through external hosting (&lt;\u20ac0.06\/kWh) or photovoltaic self-consumption.<\/li>\n<li><strong>Can you mine profitably without an ASIC?<\/strong>Not on Bitcoin. On altcoins, it is possible with GPU, but the net profitability after paying for electricity is usually marginal or zero.<\/li>\n<li><strong>What happens when the next halving arrives?<\/strong>It halves the block reward (the next one will be in 2028, dropping to 1.5625 BTC). If the price does not rise or difficulty does not drop, inefficient miners shut down their equipment.<\/li>\n<li><strong>Is it legal to mine in a residential apartment?<\/strong>Yes, it is fully legal, as long as profits are declared and local regulations on noise, heat, and contracted power limits are respected.<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-33541\" src=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2026\/09\/7-1-1024x683.jpg\" alt=\"\" width=\"700\" height=\"467\" srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2026\/09\/7-1-1024x683.jpg 1024w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2026\/09\/7-1-300x200.jpg 300w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2026\/09\/7-1-768x512.jpg 768w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2026\/09\/7-1-1536x1025.jpg 1536w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2026\/09\/7-1-2048x1366.jpg 2048w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<p>In conclusion, determining whether\u00a0<strong>cryptocurrency mining<\/strong>\u00a0should be approached as a\u00a0<strong>home project<\/strong>\u00a0or a\u00a0<strong>professional operation<\/strong>\u00a0does not depend on the equipment&#8217;s raw power, but on the operational and geographical context: while the industrial miner competes through\u00a0<strong>economies of scale<\/strong>, dedicated infrastructure, and low-cost wholesale electricity rates,\u00a0<strong>residential mining<\/strong>\u00a0remains severely restricted by conventional grid electricity prices, thermal limitations, and unsustainable noise levels for a domestic environment.<\/p>\n<p>Therefore, the technical and financial viability of a\u00a0<strong>rig<\/strong>\u00a0is defined by the logistics of where it is installed, the agreed energy rate, and the tolerance margin for heat and noise, making the environment the key factor in the success or failure of the investment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Tiempo de lectura:<\/span> <span class=\"rt-time\"> 7<\/span> <span class=\"rt-label rt-postfix\">minutos<\/span><\/span>Bitcoin mining difficulty dropped 14% this year.
