Boosters seem to be the answer..

Before I start, if you're going to use profanity in your nickname or comments, don't bother commenting. I'll report you.. Rather than worrying about not receiving rewards because I'm spending 1,000 gems on an amount of money that far exceeds the money vault's limit, I assume the money double booster inflates money by 100 times, right? Because it's Revenue x10 and Speed x10? If that's the case, it's 20 gems for revenue and 40 gems for speed. With 1020 gems, I can activate that 100x revenue 17 times? ㅋㅋ Isn't that more profitable than buying with 1000 gems? Also, instead of upgrading the Raw Material Plant to level 3 and the Mixing Plant to level 3 once each, I currently have 3 Raw Material Plants at level 2 and 4 Mixing Plants at level 2. Should I just upgrade all 4 Mixing Plants to level 3.. Level 3 Raw Material Plant produces flour, and Level 3 Mixing Plant produces bread, but without flour, bread is useless.. My eyes are on 1,000 strawberry jams for 10 million won ㄷㄷ. I'm debating whether to make bread or go all-in on jam. What's more profitable..
