Started with an old Whatsminer M30 bought on marketplace for a garage heater. Quickly realized that it was not profitable unless running for heat. Moved to hosting a few miners with Hashlabs ($.06/kwh hosting + good prices for miners) and decided to pull equity in my real estate and go all in. Now run around 4000TH and just keep rolling proceeds to buy more (adding another 600TH next week). They have been awesome to work with and have helped me scale up profitably.
