Perguntas frequentes
Perguntas frequentes
Onde comprar ASIC para mineração?
Oficialmente aos fabricantes (Bitmain, MicroBT, Canaan) ou revendedores autorizados. Links de referência levam a lojas com possíveis descontos ou bónus.
O que importa mais: hashrate ou eficiência?
Depende do preço da electricidade. Com tarifa alta, um miner mais eficiente (baixo W/TH) compensa. Com electricidade barata, considere preço por TH e hashrate máximo.
Por que equipamento e carteiras na mesma página?
Mineração e armazenamento estão ligados: o BTC minerado precisa ser guardado com segurança. Carteiras hardware (Ledger, Trezor, etc.) são recomendadas para valores grandes em vez de exchange ou pool.
Which ASIC should I prioritize in 2026?
Evaluate the bundle: J/TH, device price, your electricity tariff, and service availability. The highest hashrate alone is not always the best choice.
What J/TH level is reasonable for new purchases?
A common benchmark is up to 22 J/TH, while models closer to 18 J/TH usually provide better margin resilience.
Are used ASIC miners worth buying?
Yes, only with a meaningful discount and clear history. Always verify hashrate stability and hardware errors under load before purchase.
What should I check on a used miner before payment?
Hashboards, fans, power supply condition, temperatures, hardware error count, and any signs of overheating or repair.
Is home mining better than hosting?
For most setups, hosting is more predictable due to lower power costs and support. Home setups often hit noise, heat, and electrical limits.
How does network difficulty growth impact ROI?
As difficulty rises, BTC output per hashrate decreases, so ROI estimates without difficulty scenarios are often too optimistic.
Which costs beyond ASIC purchase should I include?
Electricity, cooling, maintenance, downtime, logistics, customs, repairs, and consumables all impact real profitability.
Do I need custom firmware for better profitability?
It can improve efficiency, but raises setup complexity and operational risk if tuned incorrectly.
How do I know an ASIC model is obsolete?
If it shows near-zero or negative margin in your base scenario at your electricity tariff even with normal uptime.
Why does secondary-market liquidity matter for ASICs?
Liquid models are easier to sell during upgrades, reducing total cost of ownership and exit risk.
Where is it safer to store mined BTC?
For long-term storage, use a hardware wallet and keep the seed phrase offline. Keep only working balances on exchanges or pools.
What should I do before final equipment purchase?
Compare 2-3 models side by side, run multi-scenario ROI, and verify warranty, service, and spare-part availability in your region.
