Undoubtedly using the Internet via satellite
I mean, obviously you
can use the internet via satellite, but this is not what blockstream satellite is. They transmit the most up to date blocks to anyone on the planet for free. You don't need to a subscription to use their service.
but there are countries where in certain places there are opportunities for mining due to cheap electricity, but access to the Internet is difficult.
Again, this is a one way transmission only. You can only receive data from the satellite, not broadcast back to it (like you would with internet via satellite). Mining via the blockstream satellite without an internet connection would be impossible - even if you found a block first, you would have no way of transmitting your block to the rest of the network, and since the rest of the network couldn't see your block, it would continue on mining as if your block didn't exist.
