Stop putting more money in. Those who can incur huge losses must have had great ambitions. They probably wanted to turn a few hundred thousand into a small fortune back then, so now they can use a few hundred to earn back tens of thousands. Following this logic, they can then achieve that small fortune. The journey has just taken a detour; the peak of life still lies ahead. Taking a step back, even if tens of thousands dwindle to just tens, it's still better than continuing to put in money and keep losing! Keep going! When the mountains and rivers seem to end, a village appears among the willows and flowers!
