/**
* Plugin Name: DCN Bilingual
* Description: Custom bilingual system for DailyCryptoNews.co — V17 Language Routing & Translation Resolver Core Fix
* Version: 1.1.0
* Author: Hermes Agent
* Text Domain: dcn-bilingual
*
* V17 CHANGES:
* - Translation Resolver (resolve_translation) — deterministic post_id resolution by language
* - Strict Guard (template_redirect) — blocks cross-language rendering
* - Homepage Query Fix — strict FR/EN isolation on homepage
* - Language Switch Fix — proper URL resolution + cache flush
* - Cache Invalidation — per-language cache isolation
* - Debug Mode — LANG_SWITCH_LOG for every routing decision

This Friday, January 9, the crypto market appears to be catching its breath after the previous day’s correction. Bitcoin is stabilizing at $90,983.52, with a near-zero daily change, while Ethereum is slightly declining to $3,104.22. Over the week, BTC still shows a gain of +2.5%, signaling that the underlying bullish trend remains intact despite the fluctuations. This stability comes amid low trading volume, typical of a Friday, when traders reduce their exposure before the weekend. Technical analysis shows Bitcoin testing the support level of $90,500, a key threshold that has previously served as a bounce point. If this floor holds, a return to $92,000 is possible on Monday. Ethereum, meanwhile, is moving dangerously close to $3,100, a level that, if broken, could lead to a drop toward $3,000. Market sentiment is cautious: fear and greed indicators are neutral at 48 out of 100. Investors are awaiting macroeconomic news, particularly Fed decisions, to take positions. In the absence of catalysts, the market could remain in a narrow range until next week.
