/**
* 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

Trump’s Veto on Housing Bill Threatens Entire Crypto Legislative Agenda
U.S. President Donald Trump has refused to sign the housing bill which contained a ban on the CBDC (Central Bank Digital Currency) , according to information confirmed by CoinDesk and CoinTelegraph on June 24, 2026. This unexpected veto could have major consequences for the Clarity Act , the long-awaited legislation intended to clarify the regulatory framework for cryptocurrencies in the United States.
The housing bill, a bipartisan text on housing, had been chosen as a legislative vehicle to discreetly pass the CBDC ban — a measure popular among Republicans who see it as an infringement on privacy and financial sovereignty. By refusing to sign, Trump removed the text from the legislative cycle, and with it all the measures attached to it.
Why This Matters for Crypto Regulation
The Clarity Act — which aims to clarify the classification of tokens as securities or commodities — was on track to be adopted. Its fate is now uncertain. Pro-crypto lawmakers will need to find a new legislative vehicle, which could take months. Meanwhile, the SEC retains its discretionary power over token classifications.
This situation illustrates the political complexity of crypto regulation in the United States: even with a pro-crypto majority in Congress, disputes over CBDCs and other related topics can stall the entire legislative process.
Pro-Crypto Candidates Gain Ground
Paradoxically, the regulatory news is not entirely negative. Three pro-crypto candidates won primaries in key states on the same day, signaling that the crypto industry is gaining political influence. These primary victories are a strong indicator ahead of the November 2026 midterms.
The contrast is striking: on one hand, legislative gridlock at the federal level; on the other, political progress for crypto-friendly candidates. U.S. crypto regulation remains an evolving issue, with each day bringing its share of twists and turns.
