In the long term, Canaan Avalon 741's destroy S9's. Canaan miners are more sturdy than the crappy built S9's but sadly Canaan was too late to join the game.
And there is that people who take the numbers on the label more seriously than the build quality of the hardware.
I mean, If you lose 3-4 of 10 S9's in the long term while you got 9/10 741's up and running you actually make more money with the Canaan miners.
**btw 741's are having a discount if I'm not wrong. Its dropped to 714$ which makes it a no brainer deal. Much better choice than s9's now.
https://canaan.io/product/avalonminer-741/ I hear everyone talk about how unreliable the Antminers is, how many have you guys lost? We have about 20 S9s/T7s/S7s and havent lost one. Are we lucky?
