常见问题
常见问题
在哪里购买 ASIC 矿机？
可从厂商（比特大陆、微比特、嘉楠）或授权经销商处购买。本页推荐链接可能享有折扣或奖励。
算力与能效哪个更重要？
取决于电价。电价高时，能效更高（低 W/TH）的矿机更划算；电价低时可考虑每 TH 价格和最大算力。
为什么设备与钱包放在同一页？
挖矿与存储相关：挖出的 BTC 需安全保存。大额资金建议使用硬件钱包（Ledger、Trezor 等），而非放在交易所或矿池。
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How do I know an ASIC model is obsolete?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.
