Why Transfer Bitcoin To Your Bank Account?
The idea that bitcoin will eventually replace fiat currencies* is the reason so many people are investing in it now. In theory, you will one day be able to use bitcoin for any type of purchase when it replaces fiat currencies, like U.S. dollars, which will no longer be necessary.
For now, however, there are still relatively few businesses or individuals that accept payment in bitcoin. That is one reason you may want to convert your bitcoin to cash—to use the value of your bitcoin to buy actual things. Another reason is when the market is in decline. If you think the price of bitcoin is going to keep sinking and you want to protect yourself from losses, it makes sense to convert bitcoin to cash while you wait for the bitcoin price to recover.
