$123 Million SUI Unlock

Also in this week’s crypto news headlines, there will be a $123 million SUI unlock on Tuesday, July 1. This round of unlocks will unleash 44 million SUI tokens, constituting 1.30% of the network’s circulating supply.

Based on data from Tokenomist.ai, these tokens will be distributed to the Sui community reserve, early contributors, the Mysten Labs treasury, and investors.

If any of these recipients cash in their allocations for early gains, it could influence the Sui price. Recent reports indicate that 90% of token unlocks drive prices down.

“Understanding unlock schedules is no longer optional for traders. It’s essential for timing market entries and exits effectively,” a recent Keyrock research highlighted.
