Investing is kind of gambling - any single program can close down for variety of reasons.
Some programs are more likely to fail than others and Bestemoneys.com seems to be low risk.

Difference between gambling with casinos and gambling with investments is that with casinos most regular gamblers will lose more than they win.
Back in the day I made ~20% - 40% profit per month for more than two years by playing with investment programs, then US government closed down e-gold.com and I lost most of my working capital.
