The performance of cryptocurrencies in 2018 was very low, so many investors withdrew from the cryptocurrency market!
The stock market is also facing the possibility of collapse, so in order to protect its assets, gold may be a good investment!
Gold is one of the most stable investments in the world, because the price is always increasing. When the crypto market weakened, many crypto owners sold it and bought gold. But speculators don't like it because the price tends to be stable, so the capital turnover is not as fast as investment in crypto. Only people who want to be quiet in investing buy gold.
