But at this stage we need to control volatility somewhat so that Bitcoin can gain confidence as a reserve asset, this can be achieved through more institutional and government adoption around the world.
Who can control the volatility, Bitcoin is a free crypto market and anyone can take action without caring about anyone.
The relevant government also sometimes exerts excessive pressure and high volatility resulting in quite extreme price fluctuations.
Now, like the US with its new president putting too much pressure on Bitcoin makes the market really fall.
This is also caused by manipulation carried out by several parties so that the price is cheaper and more to buy.
No one can really control bitcoin's volatility.
