So it's not scientific to compare bitcoin with gold.
Open a browser and go to any Bitcoin chart. Change it to a weekly chart and zoom out to the year 2010 to 2018. You can now see how Bitcoin has never lost its trajectory and it is still going up.
Plus "protection" can also mean other things. Bitcoin is also a protection against censorship because as long as your transaction is valid, no one can stop it. It can also be a protection against confiscation of property because Bitcoin is a sovereign asset that cannot be controlled by any state.
Good defense but it is still a specualtive asset at this moment. I heard some countries that treat it like currency but as an entirety, it still not considered as money. Others are still experimenting and observing.
I am not denying that it is a speculative asset. I believe it is what brings the fun in Bitcoin. Hahaha.
It should not convey that what I said about Bitcoin's censorship resistance and property confiscation protection is wrong.
