$ETH To be honest, you can't spend too much money on this. After two times, it's gone. If you have a lot of money, it’s easy to lose it on something. If you have little money, losing it doesn't matter. It's better than this messed-up market right now. If you win once and lose once, it's equivalent to losing 20% of your own money. You need to win twice and lose once to earn back 60% of your principal.
