Dont know on why you guys are really that making use of the word "investing" on which you are really just that pertaining about on making some actions in trying out to test out some new sites or platforms.
I don't understand your point here. Investing implies adding funds which is what we are talking about here.
Some might have the courage on taking up some risks and some would really be just that waiting for others feedbacks before they would really be getting in.
Well its a common approach and action made by someone but dont make yourself that be like this most of the time.
You need to understand that every site was new at some point which is why taking risks is essential in order to find out whether the site in question is legit or not. The risk factor can be minimised by sticking to small amounts initially.
