Now, what is built on top of it is currently restricted by a lack of a common goal for the community and the more than questionable ethics of its market participants including developers, users and marketers. Till this situation changes, I wouldn't call it an "investment". It is a risky enterprise with good upside potential depending on how diligent and intelligent you are.
Perception of Bitcoin determines wealth. Long-term holding will increase wealth. Don't have a fluke, don't be impetuous, and don't let your eyes and the computer screen be a couple. In short, cryptocurrency will be the most worthwhile investment project for a long time in the future, but I can tell you accurately that you will realize the freedom of wealth. This depends on your mentality and the depth of your Bitcoin knowledge.
