Canaan Avalon 1246 83TH Bitcoin Miner Asic Miner 3155W Crypto Mining Machine Much Cheaper Than Antminer S19pro and Whatsminer M30S

Purchased this item my first miner to see if it would be worth buying 50 + Asic Miners. What I was expecting, the Bitmains product reviewers have all been advertising $15 a day profit after electricity. The actual earnings after 4 days is averaging $8.75 a day (not counting the cost of electricity). I know this will fluctuate based on the value of BTC. This will make about $3,193.75 a year at current bitcoin price (not counting electricity costs I do not know how to calculate my electric expense). Will be waiting another 30 days or so before ordering more to find out if its worth the investment. Now when I purchased this machine I expected it top be loud and yes it is loud. It is a heavy duty well built machine. Wish my basement was more soundproof can hear it on the main level. Will likely be moving the unit to my office/wearhouse.
