I will invest in both of them to minimize the risks in future as making profits from gold will take really long time but its also an safest form of investment so will prefer to hold it for a long term and with bitcoin I can make quick profits taking advantage from short term fluctuations.
Investing for both thing has assured profit depending on the amount you'll invest and I've would love to choose both of it. But there are people that can't take to hold both investments because of they cannot handle risks. And if ever it is harvest time, you are the one to earn great profit just like what's happening with bitcoin.
Bitcoin is not to hold for a long time and you should take advantage from each and every fluctuation to make quick profits which is never possible with gold and to make good profits from gold hold it for a long term.
