Antminer E9 is a powerful ETH miner and yes with 30,000+$ you can get one, ASIC miner E9 is capable of 3000MH on ETH and that's  287$ per day if you use flexpool which is currently the most profitable pool but the problem is buying this ASIC and not getting scammed in the process, mind you mining profits just increased too due to surge in BTC and ETH so the 287$ won't be permanent
