/**
* 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 Sunday, June 14, 2026, the cryptocurrency market closes the week on a positive note. Bitcoin reaches $64,378, up 1.3% on the day. Ethereum follows at $1,679. Over the week, performance is solid with a 5.8% gain. Investors can breathe after a volatile week.
This bullish end to the week confirms the rebound that began on Friday. Bitcoin has managed to erase early-week losses, once again demonstrating its resilience. The macroeconomic context, though still uncertain, was favorable with hopes of more accommodative monetary policies. Late-week buying, often attributed to institutional investors adjusting their portfolios, also supported prices.
The impact on market sentiment is clear: optimism is returning. Traders see this week as a successful test, with Bitcoin bouncing back after a sharp drop. The $64,000 level is now a potential support for the week ahead. However, caution remains warranted: markets are still volatile, and macroeconomic uncertainties persist. For now, investors can savor this positive end to the week while keeping an eye on upcoming developments.
