gold price is not like bitcoin, but i think it because asset. when something happen asset will take effect, it doesnt mean that trump speech will give effect on bitcoin price, maybe it just accidental
indeed gold and bitcoin have very clear differences and price movements should be very different if there are similarities it might not be intentional, but I feel the condition of the world economy is also a very strong influence.
You can take advantage of price movements to be able to make a profit.
