On the Exchange, the trades occur between users, but on the Instant Exchange, trades are conducted with the virtual currency that Zaif possesses.
At the Exchange, trades are not completed until a trading partner accepting the price of the order appears. However, the Instant Exchange is allows for spots to be purchased at fixed prices and trades to settle quickly. (Prices may fluctuate on Instant Exchange)
Due to the fact that transactions are done in virtual currency maintained by Zaif, the maximum value for each trade is ¥500,000, and the maximum trade volume for each day is ¥50,000,000.
