This is not even about mining or holding. It’s about why you’re even here. If you don’t know why you’re in Bitcoin, the question is already answered: NEITHER. Most individuals mine because they believe working harder results in more; most people hold because they believe waiting longer results in greater success. Both are naive if you ignore the meta-game
Unlike the "decentralized" ideal folks offer you, mining is becoming ever centralized. Have you access to low-cost energy? Top-tier ASICs? Political protection against regulation? If not, you are running against individuals that do. Holding, meantime, is only another taste of market exposure. Still under the control of institutional whales, algorithmic trading, global macro cycles, and the emotional instability of other holders
Both methods can work if you internalize that Bitcoin isn’t about making you rich, it’s about making you free. Or not. Perhaps your presence here is purely financial, like most others. Then, certainly, hold if you wish not to die from electricity costs. If you have infrastructure most others lack, mine. But if you think you’ll find certainty in a system built on uncertainty, you’ve already lost the plot
