How much is alt to dollar?

Could you please elaborate on the conversion rate between altcoins and the US dollar? I'm curious about the current market value of alternative cryptocurrencies compared to the traditional fiat currency. With the volatile nature of the crypto market, it's essential to stay updated on the latest exchange rates. Could you provide a snapshot of the current altcoin to dollar ratio, and perhaps some insights into how this ratio tends to fluctuate over time? Your input would be invaluable for those seeking to navigate the complex landscape of digital assets.
