I would like to start mining, and I was considering buying BITMAIN Antminer T9.
Do you think it's good investment? I'm not looking to get rich, just a montly bonus to my salery...
Power cost is 0.08$ kWh in my country
Any advice would be great, thank you
T9 hashrate = 12,5 Th/s
T9 power draw = 1686 Watt
Your electricity rate = 8 cent/Kwu

At this moment (current diff, exhange rate and block reward), it'll take you 126 days to break even... BUT:
- the diff changes every 2 weeks (usually, it goes up, but not allways)
- the price BTC fluctuates
- the block reward will halve in a couple of years
- no "extra's" were included in the price (shipping, handling, customs fees, shelves, cooling, network, cabling,...)
- bitmain is known to have "less than perfect" customer support... They have 3 months factory warrantee, and have been suspected of selling used miners, broken miners,... Or simply not honoring their very short warrantee period at all)
Many thanks, oh the Wise one

Seriously, the information that you have given me are really more than helpful. I had no idea that bitmain is having that reputation...
Once again, thank you
