I've been investing in various memecoins, rarely seeing any with a decent whitepaper. Most seem similar, except Floki with its utilities. I prefer coins like Floki - multichain or with a good whitepaper. I've seen $WIF, $MEW & $ROSA. ROSA seems multichain but least popular.
What's your thought on $ROSA compared to others.
And is there any other CEX listing it apart from Bitci?
You won't because most of them are useless coins. And even then all you need is somebody with some sharp skills and imagination to develop a nice looking white paper. No memecoin maybe besides dogecoin because it has first mover status will last all that long. Yes you can make money because of the greed pumps but in the end they will all fall to the same price...$0
