Last week I saw the crypto market of bitcoin and altcoin all fell dramatically because there was competition in gold trading that made all prices fall, is gold investment more profitable than bitcoin and altcoin which are vulnerable to hacking.
And today bitcoin fell in price due to the fact that the price of oil rose.

I do not understand why link together something that does not have direct quotations between them. If you on one of the exchanges could buy gold directly with bitcoins, then perhaps it would make sense to say this.
