By the time some coins arrive on Binance, they have already been purchased on other platforms. Their arrival on Binance is a profit-taking, so they flood the market and the price falls. This is what happened with $BIO , this is what is happening with $SOLV , and this is what will happen with $TRUMP . It is a bad idea in these cases to buy immediately, it is better to wait a few days for the prices to become more stable.
