My real investment depends on various factors including the purpose of the project, the idea, the team, their goals etc...
If you look at the market place and the projects that started with big plans mostly every projects came crashing, some crashed because they are not getting the required license to fulfill the projects and some started as outright scams, so this is not a viable factor to invest with the promise of a good project.
Bitcoin created this entire market and if you are looking to profit trading in bitcoin you can make a good profit, investing in projects is the biggest risk as majority will turn to dust in due time and you will not find projects that stand the test of time in this market, so my advice is to never test those waters with your hard earned money.
