Hello, I would like to know which ASIC you would advise me to make a maximum profit? For information I pay 0.06€ per kWh (0.07$) and I have much money to invest.

How is the Bitmain Antminer E9, according to the site whattomine.com this miner produces 220$ per day and costs at its maximum release 30000$, is it good? in how long I can make it profitable? and in how many years it will become obselete?
