Buying an ASIC miner is a better option than buying ZEC at the current price. Based on the profitability calculation, the machine can pay for itself within approximately three months. I personally expect the price of ZEC to decline in the near future, so holding the hardware carries less market-price risk compared to holding the coin directly.

In general, any mining machine should ideally reach ROI within one year. Since this ASIC achieves ROI in about three months, the investment is considered strong and significantly safer than buying ZEC outright.
