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.
