Bitpool is a digital company that only offer their service only to European countries, countriew like America and Africa can not use the service of Bitpool, According to my findings I found out that Bitpool have stopped working on some phones and their server has also been deactivated which most of their users were unable to have access to their services.
The limitation of Bitpool mining company is many, for example Bitpool does not balance the transaction fees when mining .if you also check the company site you would found out that their are limited reviews for the company which is an indication that the company service is very poor, with these little information about their service I don't expect anyone outside of Europe to choose their service.
