Reliability vs ROI is the hot topic as two online threads collide. A Canaan Avalon Nano 3 unit is described with scorch marks and warranty headaches, and the seller doesn’t sugarcoat the struggles [1]. Meanwhile, posts hype the Bitdeer Sealminer A3 series as highly profitable [2]. Investors chase ROI while manufacturers face reliability hurdles.
Reliability reality — the Nano 3 thread paints a rough picture: months of trouble, warranty headaches, and a unit that died again. The post details scorch marks inside the power plug area and notes hands-on warranty hassles; the user says it's still under warranty but has spent hours navigating RMAs [1].
Profit hype around the A3 series — a YouTube video proclaims the Bitdeer Sealminer A3 series "SO PROFITABLE" [2]. VoskCoin mirrors that enthusiasm in a tweet tied to the same lineup [3].
What operators should trust — hype is loud, but uptime data and solid support matter. ROI chatter can’t beat real-world reliability; the Nano 3 story highlights risks, while the A3 chatter invites verification of profitability with independent data [1][2][3].
Takeaway: don’t buy on hype alone. Track uptime, warranty support, and verifiable ROI before pulling the trigger on new miners.
