Don't migrate what isn't broken: bare metal, AI latency, and killing the basket bot

When someone hands you a "better infrastructure" plan, the first question isn't "how do I migrate?" — it's "is this actually a problem?" This week I received a well-intentioned suggestion: move the grid trading bots off the M900 Tiny, spin up a €7/month Hetzner VPS, and buy a €300 Mini PC to replace the "main machine." The reasoning sounded solid until you looked at the actual setup. The non-problem The M900 Tiny (Lenovo ThinkCentre, 8GB RAM, Ubuntu 24.04) is already a dedicated, isolated machine. It runs nothing personal. The bots are Python scripts — no daemon, no persistent socket, no GPU requirement. System cron fires them every 5 minutes. Total RAM usage: ~1.2GB. For this workload, a cloud VPS would: Add a network hop for every API call to Arbitrum/Base/Linea/Solana RPCs Introduce a monthly recurring cost Create an SSH dependency I don't currently have Solve zero problems The machine is already sunk cost. It's already isolated. It already works. The advice was technically correct
