I find it quite an odd place to move. I don't know what would be the status for the hardware (do they have to pay import tax?) and what would be the taxes to be paid in US for the operations (aren't they higher than in other places?)
There are a lot of things that mitigate the import taxes and other labor costs.
One is
section 179,
Jan 6, 2021 – The Section 179 deduction for 2021 is $1,050,000 (up from $1,040,000 in 2020). This means U.S. companies can deduct the full price of qualified equipment purchases, up to $1,050,000, with a “total equipment purchase” limit of $2.62 million (up from $2.59 million in 2020). The deduction includes both new and used qualified equipment.
In addition, businesses can take advantage of 100% bonus depreciation on both new and used equipment for the entirety of 2021.
How does a 100% deduction for up to 2.6 million (that's around 300 ends of the line Asics if you know how to negotiate) a year sound? And it is also extended to used gear so it means you can simply import those from a Chinese miner once you set up an LLC and almost not care about throwing them out of the window when they become obsolete. Set up a few LLC, do a bit of tax...
improvements by arranging a few deals between them and you will end with a better profit after tax than anywhere in the world.
Plus, Texas has a lot of cheap power, the average price for energy over the state doesn't matter, most deals are made well under the commercial rates, most of the time closer to 2-3 cents rather than the 7c average for the state.
And something else: will the "Bitcoin mining is centralized in China" narrative get replaced by "Bitcoin mining is centralized in United States" (narrative)?
Miners will always migrate to the best country for their business, centralization is unavoidable no matter what anyone would try to do.
But at the end of the day, if you could choose the location of 51+% of the hashrate what would you pick? Texas, Russia, or China?
