You mean like a capital fund? Those are prevalent and more safer in real life and not online using a currency that is not even legal in many countries. Invest your money in the popular capital funds in your country and you should be happy that you did what you wanted.

But trusting someone with your bitcoin in the internet is the next worst thing to do. If you know them in real life and can legally approach them then I guess its fine, though the lawyers need to knowledgeable about it.

But blindly giving out money to someone hoping it to come back to you doubled is a scam. Dont be that noob.
