$ZEC 's Project Tachyon security upgrade can ignite a new round of uptrend?

Brothers, ZEC has been experiencing sharp fluctuations recently.
News:
Zcash is undergoing a key security upgrade — Project Tachyon has nearly completed the mathematical proof for the Ironwood shielded pool, confirming no hidden inflation vulnerability, with AI assistance reducing audits that would take years to just weeks. The Ironwood upgrade is expected to activate on the mainnet around July 21, introducing a new privacy pool and the Turnstile supply verification mechanism.
After the news was released, ZEC briefly surged above $500, gaining about 12%. However, after yesterday's spike, it pulled back to around 476, reflecting profit-taking after the market partially priced in the upgrade's positive news.
Technical Analysis:
The current price has broken below the BOLL mid-band, with RSI1 at 37.77 near the oversold zone.
Resistance above: 483-490, break above look at 500-510.
Support below: 470-472, if lost look at 456.
Gongming's View:
The Ironwood upgrade is a medium-term positive, but after the short-term spike and pullback, it needs time to digest. The area around 475 is a key defense level for bulls.
Trading Strategy:
Conservative: wait for a pullback to around 470-472 to go long.
Aggressive: go long with a small position at the current price around 474.
Security upgrades are a long-term narrative; don't chase highs and sell lows in the short term, wait for a pullback confirmation before entering.
