That's really strange for sure, the 2 things are very different but when the graphs get placed together, it looks almost identical.
Not sure what's the reason to this, but if we are following the graph it estimates that there'll be a price pump in 2020? ETF is getting very close to being completed as well...
It's pretty crazy to see a decentralizatied technical coin be very similar to a traditional fiat investment.
This may be a coincidence but this may also be destined to happen. If this will continue to happen and actually follow the way how gold showed in the graph this may be a good way for bitcoin.
Bitcoin is considered as a second gold, they have a lot of similarities, and they are also both using as a long term investment.
It will be another bullish market to come in the crypto world.
