Couldn't someone just bet 1 BTC at 98% and get the larger faucet with practically zero risk? Or they could bet 0.5 BTC at 98% two times, again with practically zero risk?
The risk is not so small, because it is gambling.
One day I played 20 games at 98% from the faucet.
4 times from these 20 the first one bet was loss. That happens.
That is a very very risky thing to do. It may seem theoretically okay, but in practice its very dangerous. I have lost large amount of bitcoins multiple time while doing those bets.
