TheCoin dot pw is a pool that allows people who prefer and use it to mine more than one type of cryptocurrency. There are many rumors about this mining. Some of these are limited access to the platform. When I went to their website and looked at it, I did not encounter anything.
More precisely, I couldn't find anything related to mining or crypto. Only 3 pictures of billiard balls greeted me and there were texts in a language I don't understand. I can say it's a pretty bad mining with no language options. More precisely, it has nothing to do with mining. I could not understand a thing, nor a single thing about them.
I also came across a small warning in my browser that it is dangerous when entering this site. As far as I know from the years when they first entered the market, they did not bad things at all, but then they could not continue this and abandoned this mining. Stay away, there is no such mining anyway.
