The Bitaxe Gamma is a hobbyist scale miner that will not produce meaningful returns compared to stacking Bitcoin directly with your existing incentive income.
The way to think about this is to treat mining as another form of speculative allocation rather than a pure ROI decision. If you want the satisfaction and learning value of running more miners then budget that as part of your discretionary spending rather than expecting the unit to pay for itself. Given your current setup the smarter financial path is likely to keep channeling the utility incentives into Bitcoin. You can expand mining only if you see it as part of the hobby or a technical project rather than a yield strategy.
The question you really need to answer is whether you value the experiential knowledge of mining more than the extra satoshis you would get from buying Bitcoin outright. Both have merit but the numbers suggest stacking will be the more efficient allocation of your already optimized energy advantage.
