Yeah as someone had already written. Dont put one egg into one baskets. Bitcoins is a good hedge against stocks and vice versa so you could have both as well as oil or other commodities which could only rise in price as they are so low.
i wouldnt be so quick to invest in oil when the world is turning to electric vehicles ,oil might go sideways for a long time because there is no shortage of it anymore.....
I wouldn't go for oil for a long haul, for certain. The rate at which alternative energy is proliferating is outright astonishing.
