PEPECASH isn't just a copy of bitcoin with a joke name like TrumpCoin or PutinCoin. It's actually Rare Pepe cards backed by the blockchain. There is a great amount of development behind it already. Unlike the fake P&D coins you're comparing it to. Here is a screen shot of an iPhone iOS app called Book of Orbs that allows you to collect, buy and sell your Rare Pepe cards using PEPECASH. There are over 700 cards created already and there will be a cap at 1000 cards. A game is currently being developed using the cards as well. This is a coin that actually has a purpose and a community behind it using it daily. That can't be said by 90% of alts.
This looks like a nice project, but it's an issued asset that resides on the XCP blockchain and so it shouldn't be compared to a currency like Dogecoin. Dogecoin has been mined fairly over time by anyone who wanted to participate, and there has been a lot of trading and diversity in the distribution.
An ICO doesn't have the same status as a widely distributed currency that has been generated gradually over time, like Bitcoin. I think that in order for PEPE to succeed, the cards should be backed by an amount of Dogecoin, so that they would always have some base value, similarly to how collector's edition specially minted coins have a dollar or other currency value to them.
