You can also bet that if the price goes down other miners would fold before your plan starts losing money so you make money even in a bear market, but that is one huge gamble and it's more on testing the company to not f*** you over as phil said.

A perfect example on how probably the only still legit company is screwing its customers right here, you can check the bitdeer plans and you're going to see:



t first nothing wrong but I was rather surprised the plan is still making that much taking into account the change in price and difficulty, so I went to the archive and surprise:



Despite the t19 being less efficient than the s19 suddenly both the rent cost per TH and the electricity cost per TH, have gone down!
From 9.37 + 8.10 cents to 8.53 + 6.75, just to make the plan more attractive.
Fairly obvious that they were simply charging extra before, fleecing the customer as much as they could.
