Pretty much everyone asks me why would I sell Frost Practice if it makes me that much money. My answer to that simply is new interests and wanting to move on from Practice/ArenaPvP gamemodes, I've been doing it for a long time so now it's become more of a chore, rather than something I fully enjoy, subsequently that ends up in lack of motivation. Currently Frost has everything a modern Practice server would need, adding new features wouldn't be required to continue making sales, but it would definitely allow it to sell even more copies.
Frost 1.19.3 was just released about a week ago, it lays on a separate repository, not a different branch on the main Frost repository (because it costs extra to get the 1.19.3 version).
I have made around $21,695.01 USD in total from selling Frost for 2 years and 2 months. $4,290.00 USD were made while I sold it through PayPal. In March 2021 my PayPal account was permanently limited and a couple days after that I started selling Frost on Tebex... The total rough estimate amount of copies sold is between 210 and 225 copies. Frost started retailing at $45.00, then increased to $60.00, later on $75.00, then $90.00, almost a year after it was $100.00 and finally $125.00.
The total amount of money made isn't taking in consideration any money made from Frost forks made privately for customers.
