Even the number of (real) miners has decreased. We had many GPU miners here in this thread, however I see no new ASIC miner guys involved in discussions.

Regarding the mobile miner experience numbers, the app says there are 150K active miners. We have no way to check and validate this number. Same goes for the number of registered users on the website. They say there are more than 2M registered users, but we are not able to check it. They can come up with any number, and we must trust them.
