The ask price is an important factor in the operation of any given market. It sets the limit for what people can sell their goods for and is a crucial link between sellers and buyers.
In finance, the "bid" price is a quote given by an investor who wants to buy a financial asset. The buyer sets this in the base currency and it's usually the maximum amount they are willing to pay. With a market order, your trade will be executed at the most advantageous price. For example, if you place a buy order it will be matched with the lowest sell order and if you place a sell order it will be matched wth the highest buy order.Trading a cryptocurrency goes through a system of orders that are set with either an take price or bid price. If you see the price of your coin as $100/$120, this means that one person is selling for $100 and another person is buying it for $120. The spread is the difference between the amount of money you'll get and the amount you'll have to pay. That difference can be really high in volatile markets. The exchange makes money and covers costs by betting on these fluctuations.
