I agree they're shitcoins but they're mostly to give people a 'stable' coin to hold funds in; it to a degree makes crypto a bit safer and friendlier to our newfriends that might get easily discouraged by losses.

so do they just represent u.s. dollars, or what the hell is the premise? ty in advance

Can't speak for them all, but the premise is to either have a stablecoin where 1 USD is forever 1 USD or perhaps have it fluctuate alongside the fiat USD value.

haha... frankly that sounds like the lamest idea i've ever heard of.

I'm neutral on it. The plus side is that they can help a lot of newcomers get into crypto without getting too rekt. The downside is everyone wants to create one.
