If bitcoin reach such ammount i would sell all my portfolio and i do believe i would retire from work and rest the last days of my life with those money, traveling as possible.
I will use a small proportion of the bitcoin I save and will enjoy a good life. I will still keep most of the coins.
Well for me i dont expect for that amount thats impossible to happen .. but if it will happen i am sure i will start a party here and start my own business. like other want to do to increase the amount of their savings.
Yeah its hard to believe that bitcoin can ever touch that price in future but if does then that would be the best time to sell our coins as we may see major price crash after that as every user will dumb his coins at that price.
