China-based Bitcoin mining firmware company, Bitmain, announced the launch of the Antminer T19 model version. This model is a cheaper version of the flagship Antminer S19 and S19 Pro models but competes favorably in efficiency of BTC mining.
#Antminer is proud to announce the new-generation #AntminerT19, the third model coming from the 19 Series. The T19 comes with a Hash Rate of 84 TH/s ± 3% with a power consumption of 3150W ± 5%. Selling period: 01 June 2020, 11:00 GMT+8 #Bitmain pic.twitter.com/sKIiaXEOuX

Bitmain releases ‘cheaper’ Antminer T19 model
After a problematic launch of the Antminer S19 models, Bitmain officially announced the launch of the cheaper Antminer T19 model which will start selling on Bitmain’s website on June 1, 2020. According to the main website the price of the Antminer T19 is $1,749 compared to S19 ($1,785) and S19 Pro ($2,407). The S19 version was sold out in minutes following the launch in 2019. The shipping of the products will start on June 21st till June 30th, the statement reads.
The Antminer T19 is the latest model in the new generation of SHA-256 custom-built chips created by Bitmain. The miner will generate a hash rate of 84 TH/s with a 3 percent variance and a power efficiency of 37.5 joules (J/TH) with a 5 percent variance. In comparison to the two flagship devices – the S19 miner produces 95 TH/s and the S19 Pro producing a hash rate of 110 TH/s. The official report further states,
“The T19 also utilizes the new APW12 power supply and upgraded firmware, which offers faster start-up speeds for an optimized mining experience.”
Bitmain, the largest Bitcoin firmware manufacturer, will limit the number of purchases to two for each user to prevent “hoarding” by the miners. Recently, Riot Blockchain, bought over 1,000 Antminer S19 model machines to boost BTC’s hash rate by 80 percent.
A solution to a failed start?
The third line in a generation of new machines gives miners hope after the terrible and troubling launch of the Antminer S19 and S19 Pro models. Users complained on abnormal failure rates of the mining firmware with nearly 20-30 percent of the total machines failing – normal failure rate is at 5%.
The dominance of Bitmain in Bitcoin’s mining is however raising questions of centralization with the company dominating the manufacturing of miners and mining the token too. Three of the largest mining pools control over half of the total hash rate and Bitmain controls two of those.
