This means, my dear, that there are locked coins that have not been offered in the market and they will be unlocked and placed in the market. The unlocking may be gradual or it may be complete.

Let's take the example of a coin $SUI .

Total coins $SUI is 10 billion.

However, the available amount is 3.25 billion.

This means that there are locked coins amounting to about 6.75 billion.

A part of it will be unlocked, approximately 88 million coins, and pumped into the market.

Note that there are some coins that are not affected... and there are coins that are affected when the lock is released and their price drops.
