Should you stack GPUs for crypto mining?

Should one really consider stacking GPUs for crypto mining? It's a popular approach, but is it truly the most efficient way to mine digital currencies? On the one hand, GPUs offer powerful parallel processing capabilities that can speed up the mining process significantly. However, they also consume a lot of power and generate a considerable amount of heat, which can lead to increased energy bills and potential hardware damage. Additionally, the crypto market is highly volatile, and the profitability of mining can fluctuate greatly depending on the price of the cryptocurrency and the difficulty of the mining process. So, is stacking GPUs the best strategy for crypto mining, or are there other options that should be considered?
