"what coin is under $5 but will net me 1000% returns?"
if anybody knew this, the coin wouldn't be under $5
you have to literally research every single coin/token out there and judge for yourself. again, the vast majority of them will fail. even the ones that make sense will likely fail. you can still get some nice little returns in the process, but there are no crystal balls to help you figure this stuff out.
the internet is full of shilling, full of FUD, full of liars, full of cynics, blind optimists, etc. everyone has a reason to pump one coin or downplay another. you have to go directly to sources and try to learn as much as you can on your own, or just look for reliable sources on various forums/youtube whatever.
