A couple of data points to help you calculate:
* active users is not the same as paying users, it's people who did something in the last month
* costs in 2020 will be something like $17,000 for hosting plus $8,000 for hardware and a few thousand bucks in travel/hotel costs to the colo. So say $30K.
* the reason hardware costs are high in 2020 is... massive expansion, so maybe people in this thread are missing something
