The 2:1 payout is this game's only saving grace. The betting UI is tedious. I get that you can put any amount you want in, but it should have buttons by units and/or percentage and a 'bet all' and save the last used bet amount, considering how repetitive it is as the game's only mechanic. The ties have no effect and are a waste of time. The medals are the only reason to play this game as per usual.

If you don't enter a bet, you go bankrupt.

The best strategy is to double your bet after you lose so that you always break even when you win. You can do the math to figure out how long of a losing streak you can survive to figure out what your initial bet should be. It's a slow grind, but it's relatively safe.
