Turning to mining fundamentals, the BTC network is secured by the SHA-256 consensus algorithm.
The most profitable SHA-256 ASIC miners currently available are; the ASICminer 8 Nano Pro, Bitfury Tardis, Bitmain Antminer S17, and MicroBT Whatsminer M215.
There is Two NEW SHA-256 ASIC miners are set to be released later this year, one of them being the StrongU STU-U8, and the other being the MicroBT Whatsminer M21.
Some manufacturers have been known to run new miners on the network prior to shipping.
Network factors that influence mining profitability include; price, block times, difficulty, block reward, and transaction fees.
Looking into electricity costs is also a significant factor when determining profitability for various ASICs.
During the flood season from April to October every year in the Chinese province of Sichuan, electricity drops to a cost of US$0.04 cents/KWh due to the abundance of hydroelectric power.
At this electricity price, all ASICs are currently profitable except the Bitmain Antminer S3.
