Yeah you have a point but however reasoning it another perspective it looks somehow because an investors shouldn't dwell on motivation from others before investing on Bitcoin however is obvious that he has already loved to invest on Bitcoin because of the potential he saw on Bitcoin so what other motivation does he need again to satisfied his curiosity, however in times of investment I think is more advisable for people or someone to have passion on Bitcoin investment instead of being motivated by people because there is a big difference between having passion on investment and having interest on investment because of motivation you get from others because we know how volatile Bitcoin can be, perhaps if the person did not see what he had expected from Bitcoin on the process it could affect his investment mindset by deciding tochange his mind on the investment but however if you are being drown to Bitcoin because how passionate you are to Bitcoin you will see that your mindset will not focus on profit making but instead it will be channeled on accumulating and holding Bitcoin for a long term.
