according to Cryptonews, Spanish legislators are calling on the country's financial regulatory agency to implement a "traffic light" risk warning system for cryptocurrencies.The system will categorize cryptocurrencies into four levels - green, yellow, orange, and red - based on their registration, support, regulation status, and market performance stability.Green represents assets with good registration, support, and regulation; yellow represents assets with "limited support" or moderate volatility; orange represents unregulated, high-risk assets; and red is used for speculative assets with "no clear issuer or substantial support."
