Gold. I think the world is heading toward the crapper with Trump in charge of the U.S., and bitcoin has proven to be an unstable pseudo-currency that is awful as a store of value. Or could be awful. It can drop as much as it shoots up, and it just might crash. Gold probably won't do that.
Because of the central control gold has got more trust than the cryptocurrencies which doesn't have a commodity state or a physical presence. Till date bitcoin have reached the value of gold on a short time of just 8years. The people who are lucky as well trusted it benefitted. One who just fluttering might have lost. I believe it's our situation that makes us believe gold better than bitcoin.
Gold is intended for guaranteed and long lasting investment. It's more of the guaranteed deposits. Any currency can fluctuate or even disappear, but gold is always in any currency of the world has a price. Bitcoin is very convenient for short-term investments and speculation due to its instability.
