Nothing if they don't like it it is their problem i would suggest that you just keep making money and let them be for what they want to be after you have made success in bitcoin they will come to you and ask how you did it then they will regret their choice.
If there is about money and bitcoin then always success of bitcoin because money is now a days generating from bitcoin because if you are holding bitcoin for long term it can make you rich in a single day so i would like to say that we should not compare money with bitcoin now a days money is the child of bitcoin because it is generating from bitcoin when we goes for withdrawal.
