pure memecoins are a pyramid scheme that will collapse as soon as 

A) the same people keep winning (as this means the average person is losing $ consistently)

and

B) new buyers entering the system are exhausted (there's a limited amount).

A is already happening (KOLs are driving token prices top down) & not sure how much of B is left.

History rhymes - exact same thing happened with NFTs.

Memecoins are less of a serious thing if you look at them like prediction markets. 

Sell = bet No 
Buy = bet Yes 
Every memecoin will end (collapse)

Unfortunately, I don't think most retail users see it this way, and they will get burned. Probably an opportunity for a safer more transparent experience.

every memecoin that is truly a memecoin(and nothing further) will most likely end, yes

and until they end they simply ride on the vibes and popularity of the cult of grifters in the center
