I'm planning to host a few miners in the coming weeks and was wondering which locations have the most famous mining facilities in the world. Could someone please let me know?
If you mean physically located mining companies, then they are located in different regions and continents, for example Hut 8 Mining Corp is located in Canada and has three mining centers, two of them are located in Alberta, and one in Ontario. Cipher Mining Inc is based in New York, but also has data centers in Ukraine, for example, Canaan Inc in China, Marathon Digital Holdings, Inc in Nevada, of course there are smaller ones.
If you mean cloud mining, then it is better not to consider it at all, since this is a common ponzi scheme.
