I believe this is a healthy way of handling your environment. Keep negativity outside your bubble. Only keep close to you people who give you the ambition and optimism to continue. Not sure how many of you believe in this. But manifesting negativity has always brought negative outcome in my life. Surrounding myself by positive thoughts and positive people has brought a strong source of light all the time.
the truth is that, if you like invest in bitcoin or not, people will always talk at you, if no one is not discouraging you or making you look like what you are doing will not yield positive result, chances are that you are heading in the wrong direction. For me, as long as I believe in what I am doing and I am very much convinced of the reason for my decision, I don't really give much attention to any external contribution as they will not see things in the angle I am seeing it and so there judgement is certainly not going to make any difference anyways.
The people you should get advice from regarding your investment in bitcoin should be individual already in the field that are more experienced than you as they might be in the best position to guide you in the right direction from the experiences they have gathered.
