$150 is the total prize fund of the Funfury competition, which means that this amount is distributed among the top 300 participants. By the way, the top 1 gets only $19.5, the top 2 gets $10.5, and the top 3 gets $4.5. All other winners get $2.625 or even less. So I wouldn't say that the prize for the top 1 is significant for the winner, although $19.5 should be enough to try all in-house games and get familiar with the Befury platform.
