Not easy to know anyone what is going on others mind. Why Satoshi created Bitcoin is up to him but situation is after created which way Bitcoin is going. Bitcoin needs transaction confirmation which is mining and don't even know any third person.

Well to be honest, the volatile nature of cryptocurrency gave people no choice than to use it as an investment option where they take profits due to the up and down movement of the market. No doubt, the concept behind cryptocurrency was to provide flexibility but the current state of the market dosen't promote that due to many reasons such as Network clogging leading to delayed transaction processing, the volatility nature that might made a person loose monetary value in a short time. I hope the cryptocurrency market gets better
