Bid-ask spread is the difference between the highest bid and the lowest sell price. A low liquidity market will have a wide bid-ask spread that indicates low volume. So, market makers enable tighter bid-ask spreads to increase liquidity and volume.

The same formula applies to cryptocurrency trading too. Crypto-based businesses are currently the best ways to earn. Especially, P2P exchanges created with the assistance of a P2P exchange development service provider are helpful for financial operations.
