Why does the 5 year bitcoin chart look so similar to the 50 year gold chart?

Here is btc from 2016-2021 and Gold from 1970-2021I’m a bozo and I really don’t know what to make of this, tbh probably just a visual correlation. ButI think its pretty cool.https://bit.ly/3xyxB9R via /r/Bitcoin https://bit.ly/3p7ddbY
