Crypto expert Toni Pizzino warns that altcoins could be in for a rough time if Bitcoin breaks below the $23,600 support level. This is because Bitcoin is still the dominant cryptocurrency in the market, and altcoins tend to follow its lead. If Bitcoin sells off, altcoins are likely to see even bigger price swings. Altcoin investors should be aware of this risk and should take steps to protect their portfolios. For example, they may want to consider reducing their exposure to altcoins or diversifying their portfolios into other asset classes. It is also important to remember that cryptocurrency is a volatile asset class. Investors should only invest what they can afford to lose and should have a long-term investment horizon.
