I suggest you don't actually invest in this. It's a waste of time and money. No, a site with the domain ".website" does not actually have data centres where they mine bitcoin. They just use new deposits to pay the old ones until they are satisfied with their earnings. Then they run.
I dont get any substance in the bold part of your logic. .website domains are indeed more costly than .com. The I am not arguing that they're not ponzi. The ponzi is still running and paid on last Monday too...
