I know many retail investors are shorting Bitcoin, thinking that it has risen enough. There are also many people who have bought a bunch of altcoins, believing that once Bitcoin finishes rising, it will be the turn of altcoins to rise, because this is how normal people think, including myself. When everyone thinks this way, things won't develop as desired. The 80/20 rule applies; only those who can buy Bitcoin no matter how high it goes, $BTC , can make money. Think in reverse! $BTC
