Avalanche’s AVAX fell more than 8% one day after the Helicon upgrade went live on Avalanche mainnet on September 22, retreating from about $11.40 to $10.36 and briefly reaching $10.11. The timing does not establish that Helicon caused the decline; price action instead suggests traders took profits after AVAX rallied from below $8 toward major resistance. Helicon introduced six changes covering network performance, staking and transaction fees: validators can automatically renew their stake, the minimum staking period fell from two weeks to 48 hours, and the reward-eligibility uptime requirement rose from 80% to at least 90% of a selected staking period. The upgrade also allows blocks to be approved while earlier transactions are still processing. Avalanche developers said the staking-reward formula will adjust gradually over 90 days, slightly reducing AVAX inflation while continuing to reward long-term staking. AVAX remains above its short- and long-term trend levels, but must hold the $10 area to regain momentum toward resistance at $11.40-$11.65. A break above that range could put $13.50 in view, while a failure could expose support around $9.50-$9.75 and then $8.70-$8.85. Bybit’s support for Avalanche v1.15.0 is a separate exchange infrastructure development covering AVAX and Avalanche C-Chain operations.
