most depin threads skip straight to the yield number and skip the part where someone has to keep a physical machine online for a year straight. that part is the whole job.
the people who benefit most from this are rarely whales with fifty nodes. more often it's the person with three nodes who has a full time job unrelated to any of this.
migrating a flux node to new hardware without losing your confirmation streak takes more planning than people expect. do it wrong and you're starting a fresh node from zero instead of continuing an existing one.
one flux node is a hobby. ten flux nodes is a part time operations job, even if the hardware barely changes. the jump from one to ten is where most people underestimate the actual workload.
the wallet holding your node collateral is the single most attacked part of running a flux node, not the node itself. people harden their server and leave their seed phrase in a notes app.
