Most exchanges have an option that protects clients from unexpected market developments. When a purchase requisition or digital currency is rounded, the price at which the trade will take place is determined for a predetermined period. Typically this period is 30 minutes: 15-20 minutes to implement the application and another 15 minutes to exchange.
This option can be used to buy or sell crypto funds during strong changes that bring in much greater market price gains. For example, consider the decrease in the bitcoin estimate that occurred on September 24, 2019.
