so how do we know that crypto exchngers dont sell us the coins what they dont exisit?
and how do we know those big funds who bought or pretinding to buy or sell some big ammounts of cryptocurrency `?
how do we know they dont lie us ?
I don't even know that there are such fake coins bought sometimes.
Just avoid treading too far in those exchange that aren't that known and probably you would feel comfortable enough to buy more.
Check its reputation globally, because I am pretty sure that exchange with fake reviews exist and they could be reviewing through Youtube videos or any sorts of paid articles.
You can't just tell a fake exchange by looking at the site with the naked eye, OP.
