Ahh, yes, there it is. I thought I remembered giving you this advice, but I couldn't find the discussion in this thread.

AWS and GCS have the same pricing structure, generally speaking. If you hosted the files on either of those platforms, it would cost approximately US$20 per month. This is not the same as hosting your files on a VPS. Accessing and transferring the files would be much quicker compared to using a VPS.

I believe you have previously stated that you don't want to use AWS because you don't want to have to use a credit card to pay, nor associate your IRL identity with the service. My argument would be that this is really your only option, as using a VPS with a smaller provider (as you have been doing) is eventually going to result in your account being shut down, or your bandwidth being exhausted.

There might be other cloud storage providers that can offer storage buckets at a lower price that might not be as reliable or have as high of throughput that offers their services for less. Your project is not one that is critical to always have access to all your data at a moment's notice, so this may be okay. It is possible you can find one that will be willing to accept crypto for their services.

If you use a storage bucket on AWS or GCS, someone will need to pay $0.09/gb to transfer the file to the internet, or $0.01 to transfer your file to another data center run by the same cloud provider located on the same continent where your data is housed (or $0.00/gb -- free - within the same datacenter location). You can configure the storage bucket so that the person downloading the file will need to pay the transfer charges.
