What kind of guide/strategy are you expecting to investing?
As you know, many of these investor-based games are scams. In the beginning it might be trustworthy and you might reach your ROI, but it's just a matter of time before they decide they have enough sitting in the wallet to run away with it.
The only solid advice anyone could give about handing your hard earned money to a stranger is only throw what you can afford to lose. You never know when they will pull the plug. It's a huge risk, but many people find it fun hoping they will make a profit before it crashes.
