If the prize is 0.1BTC what would you do? Split the prize and walk away with 0.05 or Reroll to gamble for the full prize?
In slots or roulettes, there are sometimes options to reroll the win amount on that spin for a chance to make it double. Sometimes if the said win amount on that spin can't be hurt to lose, I always try my luck to gamble that amount.
In that situation you have shared, it's already BTC0.05 guaranteed prize and that was a giveaway. I don't know if someone has the guts to still pursue the full prize. It's already a sure win and should be grabbed right away.
From the point of view of the mathematical theory of probability, both options are beneficial to the player. The second option is essentially a continuation of gambling in order to maximize your winnings.
In roulette, you can also bet on red/black and win/lose with a 50 percent chance. At the same time, in the second option, there are no casino commissions (there is no zero sector).
In fact, everything here depends on the ambitions of the player.
Many people strive for a big win and do not want to be content with a small amount of money to win. It is reasonable.
