Bitcoin is too unstable to be used as reserve asset
Prices have been fairly stable in the last years in bitcoins. The volatility isn't higher than in some previous metal markets, prices on commodities are fluctuating too with the general market sentiment. Bitcoins might not be the best reserve asset but it's definitely one. There are even companies now who use bitcoins as reserve asset.
No, that is not enough for bitcoin to become a reserve asset. It needs to be stable in a large amount of time. Look at how bitcoin performed in March and April, the price was reduced to one third and suddenly it was pumped up to $9000. And right now, the price of bitcoin is $14000. We are nearly reaching our previous peak and that is a good sign for bitcoin. But becoming a reserve asset is way too beyond its purpose and it might take several years for bitcoin to be adopted regularly. As you can see, there are many people who do not like bitcoin and without their support, it is hard for bitcoin to make a dramatic impact on our economy. And companies which consider bitcoins as reserve asset does not strong enough to have their own speech
Don't expect in bitcoin too much. One day it might be replaced by another digital asset which is stronger, better, and safer. Just try to accumulate bitcoin and sell it at a good price and always remember to support the blockchain technology with your own heart
