Yes. Bitcoin is already replacing gold, look at the price. The is not for no reason either. It is because Bitcoin is a better store of value than gold for storing long terms of wealth.
Nope. Like most people are saying, bitcoin and gold are different. Bitcoin can be used online, by sending funds globally without any borders. Gold can be used to make jewelry. The only similarity is that both are sometimes being used as store value. Also, price is not a factor when deciding if bitcoin replaced gold or not. The iPhone 8plus is slightly more expensive than the Galaxy S8, but it doesn't mean the iPhone is better; it just depends on people's opinion/s.
