the market is slow and dumped and waiting for a bull run that will start by the end of 2021 or starting from January 2022, so wait and hold your altcoins for the bull run.
Yeah you are right, bitcoin market has already started its bull run recently like you have mentioned and it may continue its rally with the help of institutional investors toward $100k or beyond that. So, there would be very very lesser chances for bitcoin be dumped harder from this point and for next 3 to 5 months.
once FUD enter the scene, those weak hands investors will eventually going to dump their shit because they always think that bitcoin is like what happened in 2018.
Not just FUD, even when technical analysis shows about possible correction then we are seeing hard dumps to happen. Usually after strong rally, crypto markets do go for downfall trend when people start profit booking.
