This coin seemed hot sometime ago. But suddenly it dumped so much.
this is how all the altcoins have always worked.
they are "hot" for some time during which time they get pumped and their prices continue to rise. the duration may be different but they all go through it.
then they get dumped like this coin. again the duration of the dump can be different but they all get dumped because after a pump there is no other option but to be dumped, it is not avoidable.
if you check the charts of the pump and dump coins you can always see the reverse V pattern (Λ) in them.
