Most of the answers I have read from the Op question, have not answered it. Though some are good. Op asked a simple question which is in the below quote.
Is there a wallet that stores more than one crytpo on your desktop?
and I don't think there is such wallet does exist, we are talking about one wallet hodling different cryptocurrency inside.
Please read other replies in the thread before posting nonsense.
I think it is not possible. All the projects (coins) has their own wallet to hodle their coin. And if Op is looking for a wallet that he can use to hold or store his coin on a desktop computer, then, it would be a wallet like "Trustwallet" because in Trustwallet there are different wallet addresses which one can use to store different cryptos but even at that the coin can't be stored in one wallet but in separate wallets. Therefore I don't know where one wallet can be used to store different cryptos.
I'm sure he meant wallet software, not a single network (blockchain) wallet. But even if it is the latter, your statement is still not true. There are numerous wallets that support multiple crypto assets. For example, most wallets that communicate with the Ethereum blockchain support multiple crypto assets (tokens) on a single address. ETH, USDT, USDC, DAI, SHIB... to name a few.
