Altcoins are dead altcoins without quantities, and no investors are interested in them. So be careful about these altcoins and don't invest in them, because no matter how long you keep them, you're never going to make a profit from them. Looking for successful altcoins with a high volume to invest is great, and if the market collapses, if you want, you can sell it easily. Never fall for low liquidity shitcoins.
