Of course it's hard. If it were easy we would all have Warren Buffett's bank account...
What I mean is that there's no public information to analyze - a website if you're lucky. There's no financial records to pore over like balance sheets, earnings reports, etc.
Due diligence is a lot of work but in these cases it's hard to even attempt it.
If there is no information or transparency, do not invest your money. Here's some advice I was told when I first started trading securities... There is one fool in every trade. No shame in being the fool if you know you are the fool and accept the trade anyway because it brings you closer to whatever goal you have. Blindly entering a trade having no idea who the fool is will lose you money every time.
I agree. I trade securities as well, largely self taught. When I was starting out and having trouble I would read books on trading and investing for information and inspiration. In one of the Market Wizards books one of the traders says something like 'people get what they want out of their trades. Some people enter trades knowing they'll lose because they're actually seeking that feeling of losing for whatever reason.'
