TokenInsight released a report this week to compare the miners in the current market, and selected five best-performing miners in consideration of halving. The factors examined include the annualized return on investment (ROI), the static return period and the shutdown price (the operating cost of the mining machine per day / the number of cryptocurrencies mined per day). These 5 miners are: 1. Antminer T17 + of Bitmain: 2. Antminer T17e of Bitmain; 3. AvalonMiner 1146 of Jianan Yunzhi; 4. Antminer T17 of Bitmain; 5. Antminer S17e of Bitmain. The report also pointed out that high-efficiency miners did not perform well in the second quarter, but still outperformed other mainstream miners in the third quarter. Such miners can better respond to electricity price fluctuations and are becoming a trend.
