It seems you're right. Bitcoin and altcoin bullish trend was a coincidence in the bullish trend to the price of gold.
Gold as of now was in 5.79% in 24 hours volume in the market.

While Bitcoin price volume is 11.19% at this moment.

The most anticipated event was now leading to going to be true. Holders now happy to see their portfolio that have profit if they invested Bitcoin last month at range of $8k.
