Savings your money to fiat is not the way to end Bitcoin volitility. I think one of solution to solving volitility issue could be through Bitcoin liquidity.
It is obvious that few people in the world today own a good percentage of Bitcoin in circulation and also not all Bitcoin is mine.
Now, liquidity refers to how easy it is to buy or sell something, without changing its price. When there’s not much liquidity, that means only a few people are willing to sell or a few are willing to buy.
Many of the largest Bitcoin holders were unwilling to sell under any circumstances. So if someone tried to buy a lot of Bitcoin at once, there wouldn’t be enough available. This would push the price up until more people sold.
The same happens in reverse. If a lot of people decide they want to sell their Bitcoin at the same time, there might not be enough buyers. Prices might then drop, until the lower price attracts more buyers.
And when more people than ever are buying and selling Bitcoin, so there’s more liquidity in the market. This helps to even out prices and might end volitility.
