Earnings from OTS nowadays

I wonder how big is OpenTibia market.

Do you think it is possible to make 120k PLN (about 30k $) per month from OTS?
Anyone one know, more-less how big are earning of top server like medivia, hexera, pbotwars, megatibia, underwar etc. from otservlist?
What is average earnings from server with about 300-400 players online?

Well.. Masiyah.se has around 1k players at weekend so i think he dont get 30k$ per month. Impossible , he got maybe 5-10k USD per month its not same Nowdays like ago

Tbh I opnened a global ot for a little while, it didn't have a lot of people, only 3 teams (around 60 players) and I got around $450/month (donations were in BRL, so mind the conversion) while it was open. For servers with 1k+ players and a lot of teams, one the opening month it's not far fetched to get around more than 10k

And from what I heard, last year pokexgames made more than one million BRL, it's not an OT but still derived from Tibia.

1 milion BRL in year is 322.534 $ in year, which means 26.878 $ per month which is close to 30k $.
Thanks then, I will probably go with Pokemon OTS instead of Dragon Ball.
