what you say is reversed, FIAT is still good, what value is down?
even altcoins that only have a pair with USDT even remain stable and can still go up, precisely if the pairing with btc altcoin will worsen the atmosphere, people still sell altcoins with btc pairs, then they sell again with FIAT pairs. that's the plot. If it is intended for investment, it will be seen that BTC and Alts look good. But to get ROI, I'm sure you will definitely return everything to FIAT
