There are two ways for you to earn passive income whether you want to invest on a count for short term or long term basis. If short term, I suggest you go with the flow of the pump happening to $Shib but if long term, look and keep an eye of this following altcoins such as $Matic, $Sol, $Dot, $XRP.
A very worthy suggestion to consider although for long term I prefer to choose Bitcoin, Ethereum and BNB, but I also like to choose coins like $Matic, $Sol, $Dot, $XRP for daily trading and also for short term because I am the same absolutely dislike coin memes like Shiba inu.
