Quick advice

• Best bang for coins right now: USB Spark Miner → Tin Spark Box → Copper Coil Rig.
• Glacier Coolant Tower is a surprisingly good deal for its size (better efficiency than Silver/Nickel/Coolant).
• The very high-end ones (Plasma, ASIC, Ion) are noticeably more expensive per H/s — only buy them if you need the big absolute power jump and have coins to burn.

Starter Node is free (best possible value) and already owned.
Copper Cache and the Seasonal/Battle Pass miners are not direct coin purchases.
