with the world being constantly in a state of upheaval there's really no way one can't be invested. that being said, Mr Buffet has a strategy of buy and hold for the long term growth of capital and investing in cash businesses such as insurance, travel and energy. I believe following that strategy and system is the best for potential growth and phenomenal roi. just my humble opinion though.
good luck out there, and remember this ain't for the weak! 😃
