my main question is : how long it'll last before it's too difficult to profit ? thanks

Hello ,

i'm thinking about buying a 13TH/s miner @ .98w/ghs for $2,700

so is it worth it

i mean how many years it'll last before it's too hard to mine bitcoin @ the wattage level ?

and lets say after a year i buy another one will it make a different or it'll be stupid ?
