/**
* 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

Bitcoin gave up ground this Wednesday, trading at $64,074, down 0.8% on the day and 5.1% on the week. Ethereum follows the trend at $1,853, reflecting widespread selling pressure across all digital assets. Trading volumes remain moderate, a sign of increased caution among investors.
This decline occurs in a tense macroeconomic context, where fears of monetary tightening persist in the United States. Traditional markets, particularly the S&P 500, also fell, reinforcing the idea of a global risk-off move. Crypto investors, often sensitive to abundant liquidity, appear to be adjusting their positions amid uncertainty over interest rates.
For observers, this weekly decline of more than 5% is a reminder of Bitcoin’s historical volatility, but also its growing correlation with traditional risk assets. In the short term, the psychological $60,000 threshold could become a key test if the downtrend continues. The coming days will be decisive in gauging the market’s resilience.
