I don't think its a good idea to discuss about crypto and bitcoin investment's  with friends because at any point in time at the sight of your rapid progress jealousy and envy may kick in at any moment.So I think it's best to discuss on topics relating to sports and politics rather than your financial life.As for me I have few friends which we all grew up together as kids and I don't keep anything away from them because we have really helped ourselves in so many ways.When it comes to income and side hustles we are open to each other and if there is any way anyone can help the other we always put in effort.We trust ourselves and also share other possible means of income with one another in other to  achieve a greater goal and build a stronger bond.
