crypto_history Optimization (PENDING ⚠️)

• Run initial query to check row count and date range
  • Total: 2,343 rows
  • Range: 2026-02-11 → 2026-03-03
• Delete rows older than 7 days
• Run final query to confirm remaining count

Warning

Tabelul crypto_history are 2,343 rânduri și generează un oxmysql oversized query la fiecare SELECT *. Trebuie adăugat LIMIT sau șters periodic.

SQL de curățat:

DELETE FROM crypto_history WHERE created_at < DATE_SUB(NOW(), INTERVAL 7 DAY);
