Similar to the situation with monero.
Not sure if you mean that Monero is afflicted by this
culture of greed, or is trying to get above it.
I know for a fact that a certain Monero dev who used
to bash "shitcoins" took part in altcoin pumps
and dumps at the same time, and I suspect he wasn't the only one.
I mean it was started by a scammer but taken over by a new developer.
But I am interested in who took part in an altcoin pump and dump and what the evidence for that is.
