can probably do actually
im gonna say this in the context of pokemon scarlet/violet, but if you completed the game, got 7 and 6 star raids, and just sat there for 24 hours winning these raids, there's a good chance that you could rack up enough loot to sell and possibly gain enough money to reach the amount specified
I can spend about 30 minutes doing raids and the rewards I rack up could get me about 200k, and that includes the losses and times when I couldn't enter a raid
